XTR101APG4

Sensor And Detector Interfaces Overview

The XTR101APG4 is a precision, low-drift two-wire transmitter manufactured by Texas Instruments. It integrates a differential input amplifier, voltage-to-current converter, and internal reference to transmit sensor signals over a two-wire loop. The device operates on a supply voltage ranging from 11.6 V to 40 V and supports an output current range of 4 mA to 20 mA. It features a maximum input bias current of 150 nA and functions within an operating temperature range of -40°C to +85°C. The component is housed in a 14-pin Plastic Dual In-Line Package (PDIP) designed for through-hole mounting.

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance status as per manufacturer documentation. Confirm package integrity upon receipt, ensuring the 14-PDIP form factor matches design requirements. Cross-reference the manufacturer part number against official Texas Instruments databases to validate authenticity and revision history before integration into production.

Sensor And Detector Interfaces Selection Notes

Select this component when a single-chip solution for two-wire loop-powered transmitters is required. Ensure the application demands a supply voltage between 11.6 V and 40 V. Verify that the through-hole PDIP-14 package aligns with the PCB layout constraints. Consider the input bias current specification if interfacing with high-impedance sensors requiring minimal loading.

Sensor And Detector Interfaces Part Context

This part belongs to the XTR101 series of precision current transmitters. The 'G4' suffix typically denotes lead-free and RoHS-compliant manufacturing variations within the same functional family. It serves as a direct replacement for earlier non-compliant versions while maintaining identical electrical performance and pinout configurations defined by the original datasheet specifications.

Sensor And Detector Interfaces Replacement Considerations

XTR101AP is listed as a manufacturer-recommended alternative. Verify that any substitute maintains the 14-PDIP package and identical electrical parameters. Confirm compatibility with existing board layouts and regulatory compliance requirements before substitution.
