TLV1543C, TLV1543I, TLV1543M 3.3ĆV 10ĆBIT ANALOGĆTOĆDIGITAL CONVERTERS WITH SERIAL CONTROL AND 11 ANALOG INPUTS SLAS072E − DECEMBER 1992 − REVISED JANUARY 2004 D 3.3-V Supply Operation D 10-Bit-Resolution A/D Converter D 11 Analog Input Channels D Three Built-In Self-Test Modes D Inherent Sample and Hold D Total Unadjusted Error . . . ± 1 LSB Max D On-Chip System Clock D End-of-Conversion (EOC) Output D Pin Compatible With TLC1543 D CMOS Technology description The TLV1543C, TLV1543I, and TLV1543M are CMOS 10-bit, switched-capacitor, successiveapproximation, analog-to-digital converters. These devices have three inputs and 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 devices allow high-speed data transfers from the host.
