    描述The TLV1543C, TLV1543I, and TLV1543M are CMOS 10-bit, switched-capacitor, successive-approximation, 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. In addition to a high-speed A/D converter and versatile control capability, these devices 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 A/D conversion, the end-of-conversion (EOC) output goes high to indicate that conversion is complete. The converter incorporated in the devices features differential high-impedance reference inputs that facilitate ratiometric conversion, scaling, and isolation of analog circuitry from logic and supply noise. A switched-capacitor design allows low-error conversion over the full operating free-air temperature range. The TLV1543C is characterized for operation from 0°C to 70°C. The TLV1543I is characterized for industrial temperature range of -40°C to 85°C. The TLV1543M is characterized for operation over the full military temperature range of –55°C to 125°C.特性3.3-V Supply Operation 10-Bit-Resolution A/D Converter 11 Analog Input Channels Three Built-In Self-Test Modes Inherent Sample and Hold Total Unadjusted Error...±1 LSB Max On-Chip System Clock End-of-Conversion (EOC) Output Pin Compatible With TLC1543 CMOS Technology
