XTR101AU/1K TI Instrumentation, OP Amps, Buffer Amps

The XTR101AU/1K is a precision, low-drift 4-20mA two-wire transmitter from Texas Instruments containing a high-accuracy instrumentation amplifier (IA), a voltage-controlled output current source, and dual-matched precision current references. The instrumentation amplifier features low offset voltage of 30µV max, low voltage drift of 0.75µV/°C max, and low nonlinearity of 0.01% max for high-precision signal conditioning. The device supports true two-wire operation with power and signal on one wire pair, providing high noise immunity against industrial interference, and operates over a wide supply range of 11.6V to 40V. The dual-matched precision current sources are ideal for sensor excitation, and the optional external transistor allows even higher precision. Housed in a 16-pin SOIC (DW) package, it operates over -40°C to 85°C. Applications include industrial process control for pressure transmitters, temperature transmitters, millivolt transmitters, resistance bridge inputs, thermocouple inputs, RTD inputs, current shunt (mV) inputs, and automated manufacturing systems.
