The AD693AQ is a Loop-powered Sensor Transmitter which accepts low-level inputs from a variety of transducers to control a standard 4 to 20mA, Two-Wire current loop. An on-chip voltage reference and auxiliary amplifier are provided for transducer excitation, up to 3.5mA of excitation current is available when the device is operated in the loop-powered mode. Alternatively, the device may be locally powered for three-wire applications when 0 to 20mA operation is desired. Active laser trimming of the AD693"s thin-film resistors result in high levels of accuracy without the need for additional adjustments and calibration. Total unadjusted error is tested on every device to be less than 0.5% of full scale at +25°C and less than 0.75% over the industrial temperature range. Residual nonlinearity is under 0.05%.
● Loop-powered operation
● Precalibrated 30 or 60mV input spans
● Independently adjustable output span and zero
● Precalibrated output spans
● Precalibrated 100V RTD interface
● Uncommitted auxiliary amp for extra flexibility
