Overview
The TLC2543CDBR is a 12-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the TLC2543 series and is characterized by its high-speed conversion capabilities and versatile control features. It is designed for communication with the serial port of a host processor or peripheral through a serial 3-state output, enabling high-speed data transfers. The TLC2543CDBR features an on-chip 14-channel multiplexer, allowing selection of any one of 11 analog inputs or three internal self-test voltages. The device incorporates a switched-capacitor, successive-approximation architecture, ensuring low-error conversion over a wide operating temperature range.
