TC7126/A  
3-1/2 Digit Analog-to-Digital Converters  
Features  
General Description  
• Internal Reference with Low Temperature Drift  
- TC7126: 80ppm/°C Typical  
The TC7126A is a 3-1/2 digit CMOS analog-to-digital  
converter (ADC) containing all the active components  
necessary to construct a 0.05% resolution measure-  
ment system. Seven-segment decoders, digit and  
polarity drivers, voltage reference, and clock circuit are  
integrated on-chip. The TC7126A directly drives a liq-  
uid crystal display (LCD), and includes a backplane  
driver.  
- TC7126A: 35ppm/°C Typical  
• Zero Reading with Zero Input  
• Low Noise: 15µV  
P-P  
• High Resolution: 0.05%  
• Low Input Leakage Current: 1pA Typ., 10pA Max.  
• Precision Null Detectors with True Polarity at Zero  
• High-Impedance Differential Input  
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.  
• Convenient 9V Battery Operation with Low Power  
Dissipation: 500µW Typ., 900µW Max.  
The TC7126A reduces linearity error to less than 1  
count. Rollover error (the difference in readings for  
equal magnitude, but opposite polarity input signals) is  
below ±1 count. High-impedance differential inputs  
Applications  
• Thermometry  
• Bridge Readouts: Strain Gauges, Load Cells,  
Null Detectors  
12  
offer 1pA leakage current and a 10 input imped-  
ance. The 15µV  
noise performance ensures a "rock

• Digital Meters and Panel Meters:  
- Voltage/Current/Ohms/Power, pH  
• Digital Scales, Process Monitors  
solid" reading, and the auto-zero cycle ensures a zero  
display reading with a 0V input.  
The TC7126A features a precision, low drift internal  
voltage reference and is functionally identical to the  
TC7126. A low drift external reference is not normally  
required with the TC7126A.
