Knowing a process or system operates, for example, within design limits is more valu-able than a direct system variable read out. A bar or moving dot display supplies information precisely with-out requiring further interpretation by the viewer.The TC826 is a complete analog-to-digital converter with direct liquid crystal (LCD) display drive. The 40LCD data segments plus zero driver give a 2.5% reso-lution bar display. Full scale differential input voltage range extends from 20mV to 2V. The TC826 sensitivity is 500μV. A low drift 35ppm/°C internal reference, LCD backplane oscillator and driver, input polarity LCD driver, and over range LCD driver make designs simple and low cost. The CMOS design required only 125µA from a 9V battery. In +5V systems, a TC7660 DC to DC converter can supply the -5V supply. The differential analog input leakage is a low 10pA.Two display formats are possible. The BAR mode dis-play is like a ‘thermometer’ scale. The LCD segment driver that equals the input, plus all below it are on. The DOT mode activates only the segment equal to the input. In either mode, the polarity signal is active for negative input signals. An over range input signal causes the display to flash and activates the over range annunciator. A HOLD mode can be selected that freezes the display and prevents updating.The dual slope integrating conversion method with auto-zero phase maximizes noise immunity and elimi-nates zero scale adjustment potentiometers. Zero scale drift is a low 5μV/°C. Conversion rate is typically 5 per second and is adjustable by a single external resistor.A compact, 0.5" square, flat package minimizes PC board area. The high pin count LSI package makes multiplexed LCD displays unnecessary. Low cost,direct drive LCD displays offer the widest viewing angle and are readily available. A standard display is avail-able now for TC826 prototyping work.Part Number Package Temperature RangeTC826CBU64-Pin PQFP0°C to +70°CAnalog-to-Digital Converter with Bar Graph Display OutputObsolete DeviceTC826DS21477C-page 2© 2005 Microchip Technology Inc.© 2005 Microchip Technology Inc.DS21477C-page 3TC8261.0ELECTRICALCHARACTERISTICSAbsolute Maximum Ratings*Supply Voltage (V+ to V-).......................................15V Analog Input Voltage (Either Input) (Note 1)...V+ to V-Power Dissipation (T A ≤ 70°C)64-Pin Plastic Flat Package...............................1.14W Operating Temperature Range:Commercial Package (C)........................0°C to +70°C Storage Temperature Range..............-65°C to +150°C*Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.

The conventional dual slope converter mea-surement cycle has two distinct phases:•Input Signal Integration•Reference Voltage Integration (De-integration)The input signal being converted is integrated for a fixed time period (T SI ). Time is measured by counting clock pulses. An opposite polarity constant reference voltage is then integrated until the integrator output voltage returns to zero. The reference integration time is directly proportional to the input signal (T RI )(Figure 3-1).In a simple dual slope converter, a complete conver-sion requires the integrator output to ‘ramp-up’ and ‘ramp-down’.A simple mathematical equation relates the input signal reference voltage and integration time:EQUATION 3-1:1RCt INT 0V IN (t)dt =V R TRI RC∫Where:V R = Reference VoltageV SI = Signal Integration Time (Fixed)T RI = Reference Voltage Integration Time(Variable)TC826For a constant V IN:EQUATION 3-2:The dual slope converter accuracy is unrelated to the integrating resistor and capacitor values, as long as they are stable during a measurement cycle. An inher-ent benefit is noise immunity. Noise spikes are inte-grated or averaged to zero during the integration periods. Integrating ADCs are immune to the large con-version errors that plague successive approximation converters in high noise environments. Interfering sig-nals with frequency components at multiples of the averaging period will be attenuated (Figure3-2).The TC826 converter improves the conventional dual slope conversion technique by incorporating an auto-zero phase. This phase eliminates zero scale offset errors and drift. A potentiometer is not required to obtain a zero output for zero input.FIGURE 3-2:NORMAL MODEREJECTION OF DUALV IN = V R T RI T SI© 2005 Microchip Technology Inc.DS21477C-page 7TC826DS21477C-page 8© 2005 Microchip Technology Inc.4.0THEORY OF OPERATION4.1Analog SectionIn addition to the basic signal integrate and de-integrate cycles discussed above, the TC826 incorpo-rates an auto-zero cycle.This cycle removes buffer amplifier, integrator, and comparator offset voltage error terms from the conversion. A true digital zero reading results without external adjusting potentiome-ters. A complete conversion consists of three cycles:an auto-zero, signal integrate and reference cycle (Figure 4-1 and Figure 4-2).4.1.1AUTO-ZERO CYCLE During the auto-zero cycle, the differential input signal is disconnected from the circuit by opening internal analog gates. The internal nodes are shorted to analog common (internal analog ground) to establish a zero input condition. Additional analog gates close a feed-back loop around the offset voltage error compensation.The voltage level established on C AZ compensates for device offset voltages.The auto-zero cycle length is 19 counts minimum.Unused time in the de-integrate cycle is added to the auto-zero cycle.4.1.2SIGNAL INTEGRATION CYCLEThe auto-zero loop is opened and the internal differen-tial inputs connect to +IN and -IN. The differential input signal is integrated for a fixed time period. The TC826signal integration period is 20 clock periods or counts.The externally set clock frequency is divided by 32before clocking the internal counters. The integration time period is:EQUATION 4-1:Where:F OSC = External Clock FrequencyT SI =32F OSCx 20© 2005 Microchip Technology Inc.DS21477C-page 9TC826The differential input voltage must be within the device Common mode range when the converter and mea-sured system share the same power supply common (ground). If the converter and measured system do not share the same power supply common, -IN should be tied to analog common. This is the usual connection for battery operated systems. Polarity is determined at the end of signal integrate signal phase. The sign bit is a true polarity indication, in that signals less than 1LSB are correctly determined. This allows precision null detection limited only by device noise and system noise.4.1.3REFERENCE INTEGRATE CYCLEThe final phase is reference integrate or de-integrate.-IN is internally connected to analog common and +IN is connected with the correct polarity to cause the inte-grator output to return to zero. The time required for the output to return to zero is proportional to the input sig-nal and is between 0 and 40 counts. The digital reading displayed is:EQUATION 4-2:20 =V IN V REFTC826DS21477C-page 10© 2005 Microchip Technology Inc.4.2System TimingThe oscillator frequency is divided by 32 prior to clock-ing the internal counters. The three-phase measure-ment cycle takes a total of 80 clock pulses. The 80count cycle is independent of input signal magnitude.Each phase of the measurement cycle has the follow-ing length:•Auto-Zero Phase: 19 to 59 CountsFor signals less than full scale, the auto-zero isassigned the unused reference integrate time period.•Signal Integrate: 20 CountsThis time period is fixed. The integration period is:EQUATION 4-3:•Reference Integrate: 0 to 41 Counts4.3Reference Voltage SelectionA full scale reading requires the input signal be twice the reference voltage. The reference potential is mea-sured between REF IN (Pin 5) and ANALOG COMMON (Pin 2).TABLE 4-1:The internal voltage reference potential available at analog common will normally be used to supply the converter’s reference. This potential is stable when-ever the supply potential is greater than approximately 7V. In applications where an externally generated refer-ence voltage is desired, refer to Figure 4-3.The reference voltage is adjusted with a near full scale input signal. Adjust for proper LCD display read out.4.4Components Value Selection4.4.1INTEGRATING RESISTOR (R INT )The desired full scale input voltage and output current capability of the input buffer and integrator amplifier set the integration resistor value. The internal class A out-put stage amplifiers will supply a 1μA drive current with minimal linearity error. R INT is easily calculated for a 1μA full scale current:EQUATION 4-4:4.4.2INTEGRATING CAPACITOR (C INT )The integrating capacitor should be selected to maxi-mize integrator output swing. The integrator output will swing to within 0.4V of V S + or V S - without saturating.The integrating capacitor is easily calculated:EQUATION 4-5:The integrating capacitor should be selected for low dielectric absorption to prevent rollover errors.
