General DescriptionThe MAX6033 ultra-high-precision series voltage refer-ence features a low 7ppm/°C (max) temperature coeffi-cient and a low dropout voltage (200mV, max). Low temperature drift and low noise make the MAX6033ideal for use with high-resolution ADCs or DACs.This device uses bandgap technology for low-noise per-formance and excellent accuracy. Laser-trimmed, high-stability, thin-film resistors, and postpackage trimming guarantee excellent initial accuracy (±0.04%, max). The MAX6033 consumes only 40µA of supply current and sources up to 15mA. Series mode references save sys-tem power and use minimal external components com-pared to two-terminal shunt references.The MAX6033 is available in the miniature 6-pin SOT23package and is offered over the automotive tempera-ture range (-40°C to +125°C).ApplicationsPrecision Regulators A/D and D/A Converters Power Supplies Hard-Disk DrivesHigh-Accuracy Industrial and Process Control Hand-Held InstrumentsFeatureso Tiny 6-Pin SOT23 Packageo Ultra-Low Temperature Drift: 7ppm/°C (max)o ±0.04% Initial Accuracy o Stable with Capacitive Loadso Low 16µV P-P Noise (0.1Hz to 10Hz) (2.5V Output)o 15mA Output Source Current o Low 200mV Dropout Voltage o Low 40µA Quiescent Current o Wide 2.7V to 12.6V Supply Voltage o Excellent Load Regulation: 0.001mV/mAMAX6033Ultra-High-Precision SOT23 SeriesVoltage Reference________________________________________________________________Maxim Integrated Products 1Selector GuidePin ConfigurationOrdering InformationTypical Operating Circuit19-2300; Rev 2; 6/03For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Note:Two-number part suffix indicates output voltage option.SOT23 Package Top Marks appear at end of data sheet.M A X 6033Ultra-High-Precision SOT23 Series Voltage ReferenceABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS —V OUT = 2.500V(V IN = 5V, C OUT = 0.1µF, I OUT = 0, T A = T MIN to T MAX , unless otherwise specified.

The extremes of these characteristics are found in theMAX6033 (2.5V output) and the MAX6033 (5V output). The Typical Operating Characteristics of the remainder of the MAX6033 family typically lie between these two extremes and can be estimated based on their output voltages.LONG-TERM STABILITY vs. TIME(V OUT = 2.5V)TIME (HOURS)V O U T (V )9008006007002003004005001002.499952.500002.500052.500102.500152.500202.500252.500302.500352.500402.4999001000LONG-TERM STABILITY vs. TIME(V OUT= 5V)TIME (HOURS)V O U T (V )9008006007002003004005001005.00005.00015.00025.00035.00045.00055.00065.00075.00085.00094.999901000Applications InformationBypassing/Load CapacitanceFor the best line-transient performance, decouple the input with a 0.1µF ceramic capacitor as shown in the Typical Operating Circuit . Place the capacitor as close to I N as possible. When transient performance is less important, no capacitor is necessary.The MAX6033 family requires a minimum output capac-itance of 0.1µF for stability and is stable with capacitive loads (including the bypass capacitance) of up to 100µF. In applications where the load or the supply can experience step changes, a larger output capacitor reduces the amount of overshoot (undershoot) and improves the circuit ’s transient response. Place output capacitors as close to the device as possible.Supply CurrentThe quiescent supply current of the MAX6033 series reference is typically 40µA and is virtually independent of the supply voltage. In the MAX6033 family, the load current is drawn from the input only when required, so supply current is not wasted and efficiency is maxi-mized at all input voltages. This improved efficiency reduces power dissipation 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 150µA 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 output 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 150ppm.Turn-On TimeThese devices typically turn on and settle to within 0.01% of their final value in >1µs. The turn-on time can increase up to 2ms with the device operating at the minimum dropout voltage and the maximum load.Precision Current SourceFigure 1 shows a typical circuit providing a precision current source. The OUTF output provides the bias cur-rent for the bipolar transistor. OUTS senses the voltage across the resistor and adjusts the current sourced by OUTF accordingly.High-Resolution DAC and Reference from Single SupplyFigure 2 shows a typical circuit providing both the power supply and reference for a high-resolution DAC.A MAX6033 with 2.5V output provides the reference voltage for the DAC.MAX6033Ultra-High-Precision SOT23 SeriesVoltage Reference_______________________________________________________________________________________9Figure 1.
