The DAC161P997-DIE is a 16-bit ΣΔ digital-to-analog converter (DAC) for transmitting an analog output current.
The data link to the DAC161P997-DIE is a single wire interface (SWIF) which allows sensor data to be transferred in digital format over an isolation boundary using a single isolation component. The DAC161P997-DIE’s digital input is compatible with standard isolation transformers and optocouplers. Error detection and handshaking features within the SWIF protocol ensure error free communication across the isolation boundary. For applications where isolation is not required, the DAC161P997-DIE interfaces directly to a microcontroller.
The loop drive of the DAC161P997-DIE interfaces to a highway addressable remote transducer (HART) modulator, allowing injection of FSK modulated digital data into the current loop. This combination of specifications and features makes the DAC161P997-DIE ideal for 2- and 4-wire industrial transmitters.
