The TLC2543C and TLC2543I are 12-bit, switched capacitor, successive approximation, analog-to-digital converters. Each device has three control inputs [chip select (CS\), input and output clock, and address input (data input)] that are used to pass serial Line 3 status output communicates with the serial port of the host or peripheral. The device allows high-speed data transfer from the host.

In addition to high-speed converters and multi-function control functions, the device has an on-chip 14-channel multiplexer that can select any of 11 inputs or any of three internal self-test voltages. The sample and hold function is automatic. At the end of a conversion, the end-of-conversion (EOC) output will be high, indicating that the conversion is complete. The converter is included in the device and features a differential high-impedance reference input to facilitate ratio conversion, scaling, and extraction from logic and supply noise Isolated analog circuits. The switched capacitor design allows low error conversion over the full operating temperature range.

TLC2543C is TA=0°C to 70°C, TLC2543I is TA=-40°C~85°C, TLC 2543M is TA=-55°C~125°C.
