TLC7135 IC - (SMD Package) - 4 1/2-Digit Precision Analog-to-Digital Converters IC

The TLC7135 converter is manufactured with Texas Instruments highly efficient CMOS technology. These 4 1/2-digit, dual-slope-integrating, analog-to-digital converters (ADCs) 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 TLC7135 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 TLC7135 is characterized for operation from 0°C to 70°C.
