Product Overview

The DAC161S997RGHT is a very low power 16-bit ΣΔ Digital-to-analogue Converter for transmitting an analogue output current over an industry standard 4 to 20mA current loop. The DAC161S997 has a simple 4-wire SPI for data transfer and configuration of the DAC functions. To reduce power and component count in compact loop-powered applications, the DAC contains an internal ultra-low power voltage reference and an internal oscillator. The low power consumption of the DAC results in additional current being available for the remaining portion of the system. The loop drive of the DAC interfaces to a Highway Addressable Remote Transducer (HART) modulator, allowing injection of FSK modulated digital data into the 4 to 20mA current loop. This combination of specifications and features makes the DAC ideal for 2-and 4-wire industrial transmitters.
  • 100µA Very-low supply current
  • 5ppmFS/°C Gain error
  • Pin-programmable power-up condition
  • Loop-error detection and reporting
  • Programmable output-current error levels
  • Simple HART modulator interfacing
  • Green product and no Sb/Br




This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
