XTR105P

Sensor And Detector Interfaces Overview

The XTR105P is a monolithic two-wire 4-20mA current transmitter manufactured by Texas Instruments. It integrates precision instrumentation amplifiers, linearization circuits, and dual high-accuracy current sources for sensor excitation. Designed for RTD temperature sensors and bridge inputs, it operates on a supply voltage range of 7.5V to 36V with a maximum operating current of 20mA. The device features a differential input type and supports an industrial operating temperature range from -40°C to +85°C. It is housed in a 14-pin PDIP package.

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'PA' or 'P' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure the procurement source provides the original Texas Instruments documentation rather than third-party summaries. Confirm that the component matches the specified 14-pin DIP package requirements for your PCB layout.

Sensor And Detector Interfaces Selection Notes

Select this component when designing two-wire transmitters requiring integrated sensor excitation and linearization. It is suitable for applications needing low total unadjusted error without external calibration. Consider the 7.5V minimum loop voltage requirement and the 14-pin through-hole packaging constraints during the initial design phase.

Sensor And Detector Interfaces Part Context

The XTR105P belongs to the XTR105 family of single-channel sensor interface ICs. This series is designed to simplify the implementation of industrial process control signals by combining signal conditioning and transmission functions into a single integrated circuit solution.
