XTR101AG-BB

Sensor And Detector Interfaces Overview

The XTR101AG-BB is a precision, low-drift 4-20mA two-wire transmitter manufactured by Burr-Brown. It integrates a high-accuracy instrumentation amplifier with a voltage-controlled output current source and dual-matched precision current references. The device operates on a single wire pair for both power and signal transmission, providing high noise immunity. Key electrical specifications include a maximum offset voltage of 30µV and a maximum voltage drift of 0.75µV/°C. It supports a wide supply range from 11.6V to 40V and functions within a specified temperature range of -40°C to +85°C. The component is available in small DIP-14 ceramic packages.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with existing system voltage requirements and load resistance constraints. Confirm that the component meets all necessary environmental and safety certifications required for the intended deployment environment before finalizing procurement.

Sensor And Detector Interfaces Selection Notes

Select this component for applications requiring precise amplification and transmission of weak sensor signals over long distances. Consider the external transistor option if higher accuracy is needed under high gain conditions to minimize thermal feedback. Evaluate the span resistor value based on the specific full-scale input voltage range to ensure the output remains within the linear operating region.

Sensor And Detector Interfaces Part Context

The XTR101 series was originally developed by Burr-Brown Corporation, a specialist in high-performance analog integrated circuits. Following the acquisition of Burr-Brown by Texas Instruments in 2000, the product line was integrated into TI's portfolio. The XTR101 represents a legacy design focused on industrial process control, maintaining its reputation for stability and precision in demanding environments.

Sensor And Detector Interfaces Replacement Considerations

Direct replacements must match the DIP-14 package and functional specifications. Verify pinout compatibility and electrical parameters such as offset voltage and supply range. Consult the manufacturer's cross-reference guide for updated part numbers or alternative grades within the same family.
