Description

The DAC161P997 is a 16-bit Δ digital-to-analog converter(DAC)for transmitting an analog output current over an industry standard 4-20 mA current loop.lt offers 16-bit accuracy with a low output current temperature coefficient(29ppm/C)and excellent long-term output current drift (90 ppmFS) while consuming less than 190 μA.

The data link to the DAC161P997 is a Single Wire Interface(SWF)which allows sensor data to be transferred in digital format over an isolation boundary usingja single isolation component. The DAC161P997'S;digital input is compatible with standard isolation transformers and opto-couplers. Error detection and handshaking features within the SWF protocolensure error free communication across the isolation boundary. For applications where isolation is not required, the DAC161P997 interfaces directly to a microcontroller.

The loop drive of the DAC161P997 interfaces to a HART(Highway Addressable Remote Transducer) modulator, allowing injection of FSK modulated digital data into the 4-20 mA current loop. This combination of specifications andfeatures makes the DAC161P997idealfor2-and4-wire industrial transmitters.

The DAC161P997 is available in a 16-lead WQFN package and is specified over the extended industrial temperature range of -40'C to 105°C.
