Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community DAC161S997 SNAS621A – JUNE 2013 – REVISED DECEMBER 2014 DAC161S997 16-Bit SPI-Programmable DAC for 4-20 mA Loops.

General Description

The DAC161S997 is a very low power 16-bit ΣΔ digital-to-analog converter (DAC) for transmitting an analog output current over an industry standard 4-20 mA current loop.

The DAC161S997 has a simple 4wire SPI for data transfer and configuration of the DAC functions.

To reduce power and component count in compact loop-powered applications, the DAC161S997 contains an internal ultra-low power voltage reference and an internal oscillator.

Key Features

  • 1 16-Bit Resolution.
  • Very-Low Supply Current of 100 µA.
  • 5 ppmFS/°C Gain Error.
  • Pin-Programmable Power-Up Condition.
  • Loop-Error Detection and Reporting.
  • Programmable Output-Current Error Levels.
  • Simple HART Modulator Interfacing.
  • Highly Integrated Feature Set in Small Footprint WQFN-16 (4- × 4-mm, 0.5-mm Pitch) 2.
