TLC1543-EP Datasheet | Texas Instruments

description The TLC1542-EP and TLC1543-EP are CMOS 10-bit switched-capacitor successive-approximation analog-to-digital converters. These devices have three inputs, a 3-state output chip select (CS), input/output clock (I/O CLOCK), address input (ADDRESS), and data output (DATA OUT)] that provide a direct 4-wire interface to the serial port of a host processor. The TLC1542-EP and TLC1543-EP allow high-speed data transfers from the host. In addition to a high-speed A /D converter and versatile control capability, the TLC1542-EP and TLC1543-EP have an on-chip 14-channel multiplexer that can select any one of 11 analog inputs or any one of three internal self-test voltages. The sample-and-hold function is automatic. At the end of the A /D conversion, the end-of-conversion (EOC) output goes high to indicate that conversion is plete. The converter incorporated in the TLC1542-EP and TLC1543-EP features differential high-impedance reference inputs that facilitate ratiometric conversion,...
