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 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. NC – No internal connection The TLV1549C is characterized for operation from 0°C to 70°C. The TLV1549I is characterized ...
