description

The TLV1549C, TLV1549I, and TLV1549M are

10-bit, switched-capacitor, successiveapproximation,

analog-to-digital converters. The

devices have two digital inputs and a 3-state

output [chip select (CS), input-output clock (I/O

CLOCK), and data output (DATA OUT)] that

provide a three-wire interface to the serial port of

a host processor.

The sample-and-hold function is automatic. The

converter incorporated in the device 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 lowerror

conversion over the full operating free-air

temperature range.

The TLV1549C is characterized for operation from 0°C to 70°C. The TLV1549I is characterized for operation

from –40°C to 85°C. The TLV1549M is characterized for operation over the full military temperature range of

–55°C to 125°C.
