TC7106/A/TC7107/A  
3-1/2 Digit Analog-to-Digital Converters  
General Description  
Features  
• Internal Reference with Low Temperature Drift  
- TC7106/7: 80ppm/°C Typical  
The TC7106A and TC7107A 3-1/2 digit direct display  
drive analog-to-digital converters allow existing 7106/  
7107 based systems to be upgraded. Each device has  
a precision reference with a 20ppm/°C max tempera-  
ture coefficient. This represents a 4 to 7 times improve-  
ment over similar 3-1/2 digit converters. Existing 7106  
and 7107 based systems may be upgraded without  
changing external passive component values. The  
TC7107A drives common anode light emitting diode  
(LED) displays directly with 8mA per segment. A low  
cost, high resolution indicating meter requires only a  
display, four resistors, and four capacitors.The  
TC7106A low power drain and 9V battery operation  
make it suitable for portable applications.  
- TC7106A/7A: 20ppm/°C Typical  
• Drives LCD (TC7106) or LED (TC7107)  
Display Directly  
• Zero Reading with Zero Input  
• Low Noise for Stable Display  
• Auto-Zero Cycle Eliminates Need for Zero  
Adjustment  
• True Polarity Indication for Precision Null

• High Impedance CMOS Differential Inputs: 10  
The TC7106A/TC7107A 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  
• Differential Reference Inputs Simplify Ratiometric  
Measurements  
• Low Power Operation: 10mW

zero display reading with a zero volts input.
