General DescriptionThe MAX6161–MAX6168 are precision, low-dropout,micropower voltage references. These three-terminal devices operate with an input voltage range from (V OUT + 200mV) to 12.6V and are available with output volt-age options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V,4.5V, and 5V. They feature a proprietary curvature-cor-rection circuit and laser-trimmed thin-film resistors that result in a very low temperature coefficient of 5ppm/°C (max) and an initial accuracy of ±2mV (max).Specifications apply to the extended temperature range (-40°C to +85°C).The MAX6161–MAX6168 typically draw only 100µA of supply current and can source 5mA (4mA for MAX6161) or sink 2mA of load current. Unlike conven-tional shunt-mode (two-terminal) references that waste supply current and require an external resistor, these devices offer a supply current that is virtually indepen-dent of the supply voltage (8µA/V variation) and do not require an external resistor. Additionally, the internally compensated devices do not require an external com-pensation capacitor. Eliminating the external compen-sation capacitor saves valuable board area in space-critical applications. A low-dropout voltage and a supply-independent, ultra-low supply current make these devices ideal for battery-operated, high-perfor-mance, low-voltage systems.The MAX6161–MAX6168 are available in 8-pin SO packages.________________________ApplicationsAnalog-to-Digital Converters (ADCs)Portable Battery-Powered Systems Notebook Computers PDAs, GPS, DMMs Cellular PhonesPrecision +3V/+5V Systems____________________________Features♦±2mV (max) Initial Accuracy♦5ppm/°C (max) Temperature Coefficient ♦5mA Source Current at 0.9mV/mA ♦2mA Sink Current at 2.5mV/mA ♦Stable with 1µF Capacitive Loads ♦No External Capacitor Required ♦100µA (typ) Quiescent Supply Current ♦200mV (max) Dropout at 1mA Load Current ♦Output Voltage Options: 1.25V, 1.8V, 2.048V, 2.5V,3V, 4.096V, 4.5V, 5V19-1650; Rev 3; 8/05MAX6161–MAX6168Precision, Micropower, Low-Dropout, High-Output-Current, SO-8 Voltage References________________________________________________________________Maxim Integrated Products 1___________________Pin Configuration*Insert the code for the desired initial accuracy and temperature coefficient (from the Selector Guide) in the blank to complete the part number.Typical Operating Circuit and Selector Guide appear at end of data sheet.Ordering InformationFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 6161–M A X 6168Precision, Micropower, Low-Dropout, High-Output-Current, SO-8 Voltage References 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Locate the capacitor as close to IN as possible. When transient performance is less important, no capacitor is necessary.Output/Load CapacitanceDevices in the MAX6161 family do not require an output capacitor for frequency stability. In applications where the load or the supply can experience step changes,an output capacitor of at least 0.1µF will reduce the amount of overshoot (undershoot) and improve the cir-cuit’s transient response. Many applications do not require an external capacitor, and the MAX6161 family can offer a significant advantage in applications when board space is critical.Supply CurrentThe quiescent supply current of the series-mode MAX6161 family is typically 100µA and is virtually inde-pendent of the supply voltage, with only an 8µA/V (max) variation with supply voltage. Unlike series refer-ences, shunt-mode references operate with a series resistor connected to the power supply. The quiescent current of a shunt-mode reference is thus a function of the input voltage. Additionally, shunt-mode references have to be biased at the maximum expected load cur-rent, even if the load current is not present at the time.In the MAX6161 family, the load current is drawn from the input voltage only when required, so supply current is not wasted and efficiency is maximized at all input voltages. This improved efficiency reduces power dissi-pation and extends battery life.When the supply voltage is below the minimum speci-fied input voltage (as during turn-on), the devices can draw up to 400µA beyond the nominal supply current.The input voltage source must be capable of providing this current to ensure reliable turn-on.Output Voltage HysteresisOutput voltage hysteresis is the change in the input voltage at T A = +25°C before and after the device is cycled over its entire operating temperature range.Hysteresis is caused by differential package stress appearing across the bandgap core transistors. The typical temperature hysteresis value is 125ppm.Turn-On TimeThese devices typically turn on and settle to within 0.1% of their final value in 50µs to 300µs, depending on the output voltage (see electrical table of part used).The turn-on time can increase up to 1.5ms with the device operating at the minimum dropout voltage and the maximum load.Typical Operating Circuit__________________________Chip Information TRANSISTOR COUNT: 117PROCESS: BiCMOSPin DescriptionPIN NAME FUNCTIONNo Connection.

Universal Voltage Monitors
The MC34161/MC33161 are universal voltage monitors intended for use in a wide variety of voltage sensing applications. These devices offer the circuit designer an economical solution for positive and negative voltage detection. The circuit consists of two comparator channels each with hysteresis, a unique Mode Select Input for channel programming, a pinned out 2.54 V reference, and two open collector outputs capable of sinking in excess of 10 mA. Each comparator channel can be configured as either inverting or noninverting by the Mode Select Input. This allows over, under, and window detection of positive and negative voltages. The minimum supply voltage needed for these devices to be fully functional is 2.0 V for positive voltage sensing and 4.0 V for negative voltage sensing.

MAXIM MAX336 MAX337 数据手册

现货库存、技术资料、百科信息、热点资讯，精彩尽在鼎好!_______________General DescriptionThe MAX336/MAX337 are monolithic, CMOS analog multiplexers (muxes). The 16-channel MAX336 is designed to connect one of 16 inputs to a common out-put by control of a 4-bit binary address. The dual,8-channel MAX337 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. Both devices can be used as either a mux or a demux. On-resistance is 400Ω(max), and the devices conduct current equally well in both directions.These muxes feature extremely low off leakages (less than 20pA at +25°C) and on-channel leakages (less than 50pA at +25°C). The new design offers guaranteed low charge injection (3.5pC typical) and electrostatic dis-charge (ESD) protection greater than 2000V, per method 3015.7. These improved muxes are pin-compatible upgrades for the industry-standard DG506 and DG507. The MAX336/MAX337 operate from a single +4.5V to +30V supply or from dual ±4.5V to ±20V supplies. All control inputs (whether address or enable) are TTL compatible (0.8V to 2.4V) over the full specified temper-ature range and over the ±4.5V to ±18V supply range.________________________ApplicationsPrecision Data Acquisition Precision Signal Routing Test Equipment____________________________Featureso <400Ω(max) On-Resistance o <500ns Transition Time o <10ΩOn-Resistance Matcho <20pA NO-Off Leakage Current at +25°C o 3.5pC Charge Injection o +4.5V to +30V Single Supply ±4.5V to ±20V Dual Supplieso Plug-In Upgrade for Industry-Standard DG506/DG507o Bidirectional Rail-to-Rail ®Signal Handling o TTL/CMOS-Logic Compatibleo >2000V ESD Protection, per Method 3015.7______________Ordering InformationMAX336/MAX33716-Channel/Dual 8-Channel,Low-Leakage, CMOS Analog Multiplexers________________________________________________________________Maxim Integrated Products1_____________________Pin Configurations/Functional Diagrams/Truth Tables19-1193; Rev 0; 4/97Ordering Information continued at end of data sheet.*Contact factory for dice specifications.For free samples & the latest literature: , or phone 1-800-998-8800Rail-to-Rail is a registered trademark of Nippon Motorola Ltd.M A X 336/M A X 33716-Channel/Dual 8-Channel,Low-Leakage, CMOS Analog Multiplexers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS—Dual Supplies(V+ = +15V, V- = -15V, GND = 0V, V AH = +2.4V, V AL = +0.8V, T A = T MIN to T MAX , unless otherwise noted.)Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The MAX336/MAX337 switches operate with ±4.5V to ±20V bipolar supplies or with a +4.5V to +30V single supply. Connect V- to GND when operating with a single supply. Both device types can also operate with unbalanced supplies such as +24V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.)Overvoltage ProtectionProper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maxi-mum ratings, because stresses beyond the listed rat-ings may cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by the logic inputs NO and COM. If power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage protection (Figure 1).Adding diodes reduces the analog signal range to 1V below V+ and 1V above V-, but does not significantly affect the devices’ low switch resistance and low leak-age characteristics. Device operation is unchanged,and the difference between V+ and V- should not exceed 44V.M A X 336/M A X 33716-Channel/Dual 8-Channel,Low-Leakage, CMOS Analog Multiplexers 6_____________________________________________________________________________________________________________________________________________________Pin DescriptionFigure 1.

2.5V, 1µA, 460kbps, RS-232-Compatible Transceivers
General Description
The MAX3316–MAX3319 transceivers have a proprietary low-dropout transmitter output stage enabling RS-232compatible performance from +2.25V to +3.0V with a dual-charge pump. These devices require only four 0.1µF capacitors, and are guaranteed to operate at data rates up to 460kbps. The MAX3318/MAX3319 achieve a 1µA supply current using Maxim’s revolutionary AutoShutdown Plus™ feature. These devices automatically enter a low-power shutdown mode when the RS-232 cable is disconnected or the transmitters of the connected peripherals are inactive for more than 30 seconds. They turn on again when they sense a valid transition at any transmitter or receiver input. AutoShutdown Plus saves power without changes to the existing BIOS or operating system. The MAX3318 is a 2-Tx/2-Rx device while the MAX3319 is a 1-Tx/1-Rx device. These devices also feature a logic-level output (READY) that asserts when the charge pump is regulating and the device is ready to begin transmitting. The MAX3316/MAX3317 are 2-Tx/2-Rx transceivers. The MAX3317 features a 1µA shutdown mode that can be entered by driving SHDN low. The MAX3317’s receivers remain active while in shutdown mode, allowing external devices such as modems to be monitored using only 1µA supply current. These devices are available in space-saving packages: MAX3316 (16-pin SSOP and 20-pin TSSOP), MAX3317/ MAX3318 (20-pin SSOP and 20-pin TSSOP), and MAX3319 (16-pin SSOP).
