4 1/2-DIGIT PRECISION ANALOG-TO-DIGITAL CONVERTERSThe 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 V and zero drift is less than 0.5 V/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 0C to 70C By Texas Instruments
