description

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.
