TC7126  
TC7126A  
3-1/2 DIGIT ANALOG-TO-DIGITAL CONVERTERS  
GENERAL DESCRIPTION  
FEATURES  
The TC7126A is a 3-1/2 digit CMOS analog-to-digital  
converter (ADC) containing all the active components nec-  
essary to construct a 0.05% resolution measurement sys-  
tem. Seven-segment decoders, digit and polarity drivers,  
voltage reference, and clock circuit are integrated on-chip.  
The TC7126A directly drives a liquid crystal display (LCD),  
and includes a backplane driver.  
A low-cost, high-resolution indicating meter requires  
only a display, four resistors, and four capacitors. The  
TC7126A's extremely low power drain and 9V battery  
operation make it ideal for portable applications.  
The TC7126A reduces linearity error to less than 1  
count. Roll-over error (the difference in readings for equal  
magnitude but opposite polarity input signals) is below ±1  
count. High-impedance differential inputs offer 1 pA leak-  
age current and a 1012Ω input impedance. The 15 µVP-P  
noise performance guarantees a "rock solid" reading, and  
the auto-zero cycle guarantees a zero display reading with  
a 0V input.  
■ Low Temperature Drift Internal Reference  
TC7126 ....................................... 80 ppm/°C Typ  
TC7126A ..................................... 35 ppm/°C Typ  
■ Guaranteed Zero Reading With Zero Input  
■ Low Noise.................................................... 15 µVP-P  
■ High Resolution ..............................................0.05%  
■ Low Input Leakage Current ...................... 1 pA Typ  
10 pA Max  
■ Precision Null Detectors With True Polarity at  
Zero  
■ High-Impedance Differential Input  
■ Convenient 9V Battery Operation With  
Low Power Dissipation ........................ 500 µW Typ  
900 µW Max  
TYPICAL APPLICATIONS  
■ Thermometry  
■ Bridge Readouts: Strain Gauges, Load Cells, Null  
Detectors  
■ Digital Meters and Panel Meters  
— Voltage/Current/Ohms/Power, pH  
■ Digital Scales, Process Monitors  
The TC7126A features a precision, low-drift internal  
voltagereferenceandisfunctionallyidenticaltotheTC7126.  
A low-drift external reference is not normally required with  
the TC7126A.
