Test Systems DESCRIPTION
The DAC161P997-DIE is a 16-bit ∑Δ 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 …
