The TLC1549C, TLC1549I, and TLC1549M
are 10-bit, switched-capacitor, successive-
approximation analog-to-digital converters.
These 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 these 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 TLC1549C is characterized for operation from 0°C to 70°C. The TLC1549I is characterized for operation
from – 40°C to 85°C. The TLC1549M is characterized for operation over the full military temperature range of
– 55°C to 125°C.
