Product Summary

The AD693AQ is a Loop-Powered 4.20 mA Sensor Transmitter which accepts low-level inputs from a variety of transducers to control a standard 4–20 mA, two-wire current loop. An on-chip voltage reference and auxiliary amplifier are provided for transducer excitation; up to 3.5 mA of excitation current is available when the AD693AQ is operated in the loop-powered mode. Alternatively, the AD693AQ may be locally powered for three-wire applications when 0–20 mA operation is desired.
