The XTR106 4-20mA current transmitter with Bridge Excitation and Linearization has low total unadjusted error, 2.5V or 5V bridge excitation reference, 5.1V regulator output, low span drift: ±25ppm/°C max, low offset drift: 0.25µV/°C, high PSR: 110dB min, high CMR: 86dB min, wide supply range: 7.5V to 36V, and is used in pressure bridge transmitters, strain gage transmitters, temperature bridge transmitters, industrial process control, SCADA remote data acquisition, remote transducers, weighing systems, and accelerometers.
The XTR106 provides a complete bridge‑excitation solution (2.5 V or 5 V reference), instrumentation amplification, sensor linearization, and a 4‑20 mA output. It operates from loop supply voltages as low as 7.5 V and up to 36 V, and is available in 14‑pin DIP and SO‑14 surface‑mount packages.
Typical applications include pressure bridge transmitters, strain‑gauge transmitters, temperature bridge transmitters, industrial process control, SCADA remote data acquisition, remote transducers, weighing systems, and accelerometers. The device offers up to 20:1 improvement in bridge non‑linearity and includes features such as high PSR (≥110 dB) and CMR (≥86 dB).
