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.
