Description
General part information
XTR106 Series
The XTR106 is a monolithic 4mA to 20mA, two-wire current transmitter designed for cost-optimized bridge sensor applications. This device provides complete bridge excitation (2.5V or 5V reference), instrumentation amplifier, sensor linearization, and current output circuitry. Current for powering additional external input circuitry is available from the VREG pin.
The instrumentation amplifier can be used over a wide range of gain, accommodating a variety of input signal types and sensors. Total unadjusted error of the complete current transmitter, including the linearized bridge, is low enough to permit use without adjustment in many applications. The XTR106 operates on loop power supply voltages down to 7.5V.
Linearization circuitry provides second-order correction to the transfer function by controlling bridge excitation voltage. The device provides up to a 20:1 improvement in nonlinearity, even with cost-optimized transducers.
