XTR105 Description
The XTR105 is a monolithic 4-20mA, 2-wire current transmitter with two precision current sources. It provides plete current excitation for platinum RTD temperature sensors and bridges, instrumentation amplifiers, and current output circuitry on a single integrated circuit. Versatile linearization circuitry provides a 2nd-order correction to the RTD, typically achieving a 40:1 improvement in linearity.
