Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community Reference Design DAC161P997 SNAS515G – JULY 2011 – REVISED DECEMBER 2014 DAC161P997 Single-Wire 16-bit DAC for 4- to 20-mA Loops.

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 (29 ppm/°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 (SWIF) which allows sensor data to be transferred in digital format over an isolation boundary using a single isolation component.
