XTR108EA/2K5

Sensor And Detector Interfaces Overview

The XTR108EA/2K5 is a smart two-wire current transmitter manufactured by Texas Instruments, designed for industrial sensor interface applications. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a typical operating current of 500 µA. The device accepts a voltage input with an input bias current of 50 pA. It generates a standard 4 mA to 20 mA output signal suitable for loop-powered systems. The component is housed in a 24-SSOP (QSOP) package with a width of 3.90 mm. It supports serial and SPI interfaces for configuration. The operational temperature range extends from -55°C to +125°C, ensuring reliability in harsh environments.

Sensor And Detector Interfaces Feature Summary

• Integrates programmable linearization capabilities for direct connection to various sensors without external calibration components.
• Supports two-wire loop-powered operation, simplifying installation by sharing power and signal lines.
• Features low input bias current to minimize loading effects on high-impedance sensor sources.

Sensor And Detector Interfaces Applications

• Industrial process control loops requiring precise 4-20 mA transmission.
• Smart sensor interfaces needing integrated linearization and signal conditioning.
• Temperature and pressure monitoring systems utilizing two-wire field devices.

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix EA/2K5 against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target system's voltage levels and communication protocols before integration. Check for moisture sensitivity level requirements during storage and handling procedures.

Sensor And Detector Interfaces Selection Notes

Select this component when a single-supply, two-wire transmitter with built-in linearization is required. Compare against the XTR106 series if bridge excitation or higher supply voltages are needed. Verify that the 24-SSOP package fits the PCB layout constraints and that the SPI interface aligns with the microcontroller resources available in the design.

Sensor And Detector Interfaces Part Context

This part belongs to the XTR108 family of smart transmitters from Texas Instruments. It is distinct from the XTR106, which supports higher voltages and bridge excitation. The EA/2K5 designation indicates the specific commercial grade temperature range and reel packaging format used for automated assembly processes.

Sensor And Detector Interfaces Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source data. Engineers should consult the manufacturer's official replacement guide or cross-reference tools for qualified alternatives that match the pinout and electrical specifications.
