Overview

The DAC8730 integrates several components in creating a smart-loop-powered sensor transmitter with
included

Highway Addressable Remote Transducer

(HART),

FOUNDATION Fieldbus

(FF), and Profibus

PA (PA) modems. The key components of the device include a 16-bit PWM DAC, loop-control operation
amplifier, HART or FF/PA modem, internal reference and power tree.
