TLC1543CFNR

Analog To Digital Converters (ADC) Overview

The TLC1543CFNR is a CMOS 10-bit successive-approximation analog-to-digital converter featuring an on-chip 14-channel multiplexer. It provides 11 selectable analog input channels and three internal self-test voltage references. The device utilizes a switched-capacitor design with inherent sample-and-hold functionality, eliminating the need for external timing components. Serial communication occurs via a 3-state DATA OUT, ADDRESS, and I/O CLOCK interface compatible with host processors. Key electrical specifications include a maximum total unadjusted error of ±1 LSB and a typical operating supply current of 2.5 mA at VCC = 5V.
