Product Summary

The ICL7135CPIZ is a 4 1/2-digit precision analog-to-digital converter. The ICL7135CPIZ is manufactured with Texas Instruments highly efficient CMOS technology. This 4 1/2-digit, dual-slope-integrating, analog-to-digital converter (DAC) is 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 decoders/drivers as well as microprocessors. The ICL7135CPIZ offers 50-ppm (one part in 20,000) resolution with a maximum linearity error of one count.
