TLC7135CN

ADCs/DACs - Special Purpose Overview

The TLC7135CN is a 4.5-digit dual-slope analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single differential voltage input and provides BCD output via a 28-pin DIP package. The device operates on a single supply voltage ranging from 4V to 6V, with an analog supply range of -8V to 6V. Key electrical parameters include a sampling rate of 3 ksps, a reference voltage of 4.75 V, and a power dissipation of 5 mW. It supports 50/60 Hz rejection and functions within a temperature range of 0°C to 70°C.
