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 4-wire 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. The low power consumption of the DAC161S997 results in additional current being available for the remaining portion of the system. The loop drive of the DAC161S997 interfaces to a Highway Addressable Remote Transducer (HART) modulator, allowing injection of FSK modulated digital data into the 4-20 mA current loop. This combination of specifications and features makes the DAC161S997 ideal for 2- and 4-wire industrial transmitters. The DAC161S997 is available in a 16-pin 4-mm × 4-mm WQFN package and is specified over the extended industrial temperature range of –40°C to +105°C.
