Product Summary
The xtr105pa is a monolithic 4-20mA, two-wire current transmitter with two precision current sources. The xtr105pa provides complete current excitation for Platinum RTD temperature sensors and bridges, instrumentation amplifier, and current output circuitry on a single integrated circuit. The xtr105pa is available in 14-pin plastic DIP and SO-14 surface-mount packages and is specified for the -40°C to +85°C industrial temperature range. Applications of the xtr105pa include: industrial process control, factory automation, SCADA remote data acquisition and remote temperature and pressure transducers.
