DAC161P997 Single-Wire 16-bit DAC for 4-20mA Loops August 2, 2011 Single-Wire 16-bit DAC for 4-20mA Loops 1.0 General 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. It 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 190µA. The data link to the DAC161P997 is a Single Wire Interface (SWIF) which allows sensor data to be transferred in digital format over an isolation boundary using a single isolation ponent. The DAC161P997’s digital input...
