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.
