CMOS Technology  
description  
The ICL7135C and TLC7135C converters are manufactured with Texas Instruments highly efficient CMOS  
technology. These 4 1/2-digit, dual-slope-integrating, analog-to-digital converters (DACs) are designed to  
provide interfaces to both a microprocessor and a visual display. The digit-drive outputs D1 through D4 and  
multiplexed binary-coded-decimal outputs B1, B2, B4, and B8 provide an interface for LED or LCD  
decoder/drivers as well as microprocessors.  
The ICL7135C and TLC7135C offer 50-ppm (one part in 20,000) resolution with a maximum linearity error of  
one count. The zero error is less than 10 µV and zero drift is less than 0.5 µV/°C. Source-impedance errors are  
minimized by low input current (less than 10 pA). Rollover error is limited to ±1 count.  
The BUSY, STROBE, RUN/HOLD, OVER RANGE, and UNDER RANGE control signals support  
microprocessor-based measurement systems. The control signals also can support remote data acquisition  
systems with data transfer through universal asynchronous receiver transmitters (UARTs).  
The ICL7135C and TLC7135C are characterized for operation from 0°C to 70°C.
