XTR101AU/1K

Sensor And Detector Interfaces Overview

The XTR101AU/1K is a precision, low-drift 4-20mA two-wire transmitter manufactured by Texas Instruments. It integrates signal conditioning and current loop transmission in a single integrated circuit. The device operates within a supply voltage range of 11.6 V to 40 V and supports an input bias current of 150 nA. It features one channel and is housed in a SOIC-16 surface-mount package. The component functions reliably across a temperature range from -40°C to +85°C. The '/1K' suffix indicates the unit is supplied in a reel packaging format.

Sensor And Detector Interfaces Feature Summary

• Integrates precision signal conditioning with 4-20mA two-wire current loop transmission capabilities
• Designed for low drift performance to maintain accuracy in sensor interface applications
• Supports operation with low-impedance bridges on the current loop

Sensor And Detector Interfaces Applications

• Industrial process control systems requiring precise current transmission
• Sensor interface circuits for pressure, temperature, or flow measurement
• Two-wire field instrumentation loops

Sensor And Detector Interfaces Procurement Notes

Verify the specific '/1K' ordering suffix to confirm reel packaging requirements before procurement. Ensure the design accommodates the SOIC-16 surface-mount footprint and respects the specified humidity sensitivity classification during storage and handling. Confirm that the 11.6 V minimum supply voltage aligns with the system power budget.

Sensor And Detector Interfaces Selection Notes

Select this component when a monolithic solution for precision 4-20mA transmission is required without external discrete components. Consider the SOIC-16 package constraints and the -40°C to +85°C operating temperature range against environmental conditions. Evaluate the 150 nA input bias current impact on high-impedance source sensors.

Sensor And Detector Interfaces Part Context

The XTR101AU/1K belongs to the XTR101 series of precision transmitters from Texas Instruments. This series is designed to simplify the design of industrial sensor interfaces by combining amplification and current loop driving. The AU variant specifies the commercial temperature grade and SOIC-16 package configuration.

Sensor And Detector Interfaces Replacement Considerations

Public documentation confirms the XTR101AU as a related variant within the same family. Verify pin compatibility and parameter alignment if substituting between package or temperature grade variations.
