TC7107A  
3-1/2 DIGIT A/D CONVERTERS  
GENERAL DESCRIPTION  
FEATURES  
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 preci-  
sion reference with a 20ppm/°C max temperature coeffi-  
cient. This represents a 4 to 7 times improvement over  
similar 3-1/2 digit converters. Existing 7106 and 7107 based  
systems may be upgraded without changing external pas-  
sive 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.  
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 offer  
1pA leakage current and a 1012input impedance. The  
differential reference input allows ratiometric measurements  
for ohms or bridge transducer measurements. The  
15µVP–P noise performance guarantees a “rock solid” read-  
ing. The auto-zero cycle guarantees a zero display read-  
ing with a zero-volts input.
