DAC161P997 Datasheet (National Semiconductor)

DAC161P997, Single-Wire 16-bit DAC

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) wh

DAC161P997 Features

* within the SWIF protocol ensure error free communication across the isolation boundary. For applications where isolation is not required, the DAC161P997 interfaces directly to a microcontroller. The loop drive of the DAC161P997 interfaces to a HART (Highway Addressable Remote Transducer) modulator,
