AD694 is a monolithic current transmitter. The input signal is buffered by an input amplifier that can be used to scale the input signal or buffer the output from a current mode DAC. The output stage compliance extends to within 2V of VS and its special design allows the output voltage to extend below common in dual supply operation. An alarm warns of an open 4�20 mA loop or noncompliance of the output stage. Active laser trimming of the device thin film resistors results in high levels of accuracy without the need for additional adjustments and calibration. An external pass transistor may be used with the device to off-load power dissipation, extending the temperature range of operation.
