XTR104BP

Sensor And Detector Interfaces Overview

The XTR104BP is a monolithic 4-20mA two-wire current transmitter designed for bridge input signals, housed in a 16-pin plastic DIP package. It integrates bridge excitation, instrumentation amplifier, linearization, and current output circuitry. The device operates on loop power supply voltages ranging from 9V to 40V with a maximum operating temperature of +85°C. Key electrical parameters include a total adjusted error of less than ±1% over the full temperature range, a minimum power supply rejection ratio of 110dB, and a minimum common-mode rejection ratio of 80dB. The output current specification covers a specified range of 4mA to 20mA.
