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.
The XTR106 is available in 14-pin plastic DIP and 14-pin SOIC surface-mount packages, and is specified for the –40°C to +85°C temperature range. The device operates from –40°C to +125°C.
