description
The TLV1549C, TLV1549I, and TLV1549M are
10-bit,
switched-capacitor,
successive-
approximation, 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 low-
error 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.
