XTR116U/2K5

Sensor And Detector Interfaces Overview

The XTR116U/2K5 is a precision current transmitter integrated circuit manufactured by Texas Instruments, designed for industrial sensor interface applications. It converts voltage inputs into standardized current outputs within an 8-SOIC surface-mount package. The device operates on a single supply voltage ranging from 3.0 V to 36 V and supports a wide operating temperature range of -40°C to +85°C. Key electrical specifications include a maximum input offset voltage of 75 µV and a gain error of 0.01%. The component draws a typical supply current of 20 mA and features internal regulation capabilities suitable for loop-powered configurations.

Sensor And Detector Interfaces Feature Summary

• Provides high-precision conversion of voltage signals to standard current loops with low offset and gain error characteristics.
• Supports flexible power architectures including loop-powered operation with an integrated 5 V regulator for auxiliary loads.
• Features robust protection mechanisms including reverse polarity protection and thermal shutdown for reliable industrial deployment.

Sensor And Detector Interfaces Applications

• Data acquisition systems converting analog sensor voltages to current standards

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'UA' against the datasheet to confirm pinout and functional compatibility, as variations may exist within the family. Ensure the ordering code matches the required tape-and-reel quantity of 2500 units. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before procurement.

Sensor And Detector Interfaces Selection Notes

Select this component when a voltage-to-current conversion with high accuracy is required in a compact surface-mount form factor. Compare against the XTR115 and XTR117 models if different input ranges or additional features like programmable gain are needed. Ensure the system power budget accommodates the 20 mA supply current requirement for proper operation.

Sensor And Detector Interfaces Part Context

This part belongs to the XTR11x family of current transmitters from Texas Instruments, which includes the XTR115, XTR116, and XTR117 variants. These devices share similar architectural foundations but differ in specific performance parameters such as input range and output configuration. The XTR116 specifically targets general-purpose precision applications within this series.

Sensor And Detector Interfaces Replacement Considerations

The XTR115U/2K5 and XTR117U/2K5 are direct family members that may serve as alternatives depending on specific input/output requirements. Verify pin compatibility and electrical parameter differences before substitution. No other third-party cross-references are confirmed in public documentation.
