TLC2543-Q1 - 12-BIT ANALOG-TO-DIGITAL CONVERTER

General Description

The TLC2543 is a 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.
