XTR106PA

Sensor And Detector Interfaces Overview

The XTR106PA is a precision sensor interface integrated circuit manufactured by Texas Instruments, designed for 4-20mA current transmitter applications. It operates within a supply voltage range of 7.5 V to 36 V and supports an operating temperature range from -40°C to +85°C. The device features a differential input type with an input bias current of 50 nA. It provides a 4 mA to 20 mA output current and includes internal reference voltages of 2.5 V and 5 V. The component is housed in a 14-pin PDIP package and utilizes through-hole mounting.

Sensor And Detector Interfaces Feature Summary

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix to confirm the package style and tube quantity. Confirm RoHS compliance status via the manufacturer's datasheet or official documentation before procurement. Ensure the selected variant matches the required PCB footprint and thermal specifications for the target application environment.

Sensor And Detector Interfaces Selection Notes

Select the XTR106PA when a robust through-hole solution is required for 4-20mA transmitter designs. Compare against surface-mount variants like the XTR106U if space constraints dictate SMD packaging. Verify that the 7.5V minimum supply voltage aligns with the system power architecture and that the PDIP-14 package fits the mechanical enclosure design.

Sensor And Detector Interfaces Part Context

The XTR106PA belongs to the XTR106 series of precision current transmitters from Texas Instruments. This series is engineered to simplify the design of two-wire loop-powered transmitters by integrating instrumentation amplification, linearization, and bridge excitation into a single monolithic device. It serves as a direct replacement for older discrete solutions in industrial instrumentation.

Sensor And Detector Interfaces Replacement Considerations

The XTR106PG4 is a verified equivalent part number offering identical electrical characteristics and functionality. Both parts share the same PDIP-14 package and pinout configuration, allowing for direct substitution in existing designs without schematic modifications.
