Overview
The TLC2543IDBRG4Q1 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 is particularly suited for automotive applications due to its qualification for such environments. It features a serial control interface and an on-chip 14-channel multiplexer, allowing it to select any one of 11 analog inputs or three internal self-test voltages. The ADC includes an inherent sample-and-hold function and supports unipolar or bipolar output operation. It is compatible with the serial port of a host processor or peripheral, enabling efficient communication through a serial 3-state output.
