Overview
The TLC2543MDBREP is a 12-bit, switched-capacitor, successive-approximation analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed for high-speed data transfers and communication with the serial port of a host processor or peripheral through a serial 3-state output. It features an on-chip 14-channel multiplexer that can select any one of 11 analog inputs or any one of three internal self-test voltages. The ADC includes an inherent sample-and-hold function and supports unipolar or bipolar output operation. It is particularly noted for its extended temperature performance, ranging from -55°C to 125°C, making it suitable for a wide range of applications.
