TLC2543,pdf(12-Bit Analog-to-D

The TLC2543C and TLC2543I are 12-bit, switched-capacitor, successive-approximaTIon, analog-to-digital converters. Each device, with three control inputs [chip select (CS\), the input-output clock, and the address input (DATA INPUT)], is designed for communicaTIon with the serial port of a host processor or peripheral through a serial 3-state output. The device allows high-speed data transfers from the host.

In addiTIon to the high-speed converter and versaTIle control capability, the device has an on-chip 14-channel multiplexer that can select any one of 11 inputs or any one of three internal self-test voltages. The sample-and-hold function is automatic. At the end of conversion, the end-of-conversion (EOC) output goes high to indicate that conversion is complete.
