XTR108TDD2

Sensor And Detector Interfaces Overview

The XTR108TDD2 is a sensor interface integrated circuit manufactured by Texas Instruments, classified as a current transmitter. It operates on a single supply voltage ranging from 4.5 V to 5.5 V with a maximum of 5.5 V and a minimum of 4.5 V. The device draws a typical operating supply current of 500 uA. It features a voltage input type with an input bias current of 50 pA. The output capabilities include a current range of 4 mA to 20 mA and a voltage output range of 500 mV to 4.5 V. It supports Serial, 2-Wire, and SPI interface types. The component is designed for operation within a temperature range of -40 C to +85 C. It is supplied in a Diesale package format.

Sensor And Detector Interfaces Feature Summary

• Provides dual-mode output capability with both 4-20 mA current loop and voltage signaling options for versatile integration into industrial control systems.
• Supports digital communication protocols including SPI and serial interfaces to enable programmable configuration and smart sensor functionality.
• Features low input bias current characteristics suitable for high-impedance signal sources requiring minimal loading.

Sensor And Detector Interfaces Applications

• Industrial process control loops utilizing two-wire transmitters
• Smart sensor interface circuits requiring digital calibration
• Data acquisition systems converting voltage signals to standard current loops

Sensor And Detector Interfaces Procurement Notes

Verify component authenticity through authorized channels due to the discontinued status. Confirm that the bare die form factor meets assembly requirements. Check for RoHS compliance variations as indicated by specific manufacturer markings. Ensure handling procedures account for the unencapsulated nature of the die. Validate compatibility with existing PCB layout constraints for die attachment.

Sensor And Detector Interfaces Selection Notes

Select this component when a bare die solution is required for space-constrained designs. Consider the QSOP-24 equivalent (XTR108EA) if packaged versions are preferred for easier assembly. Evaluate the need for SPI programming capabilities against system complexity. Assess thermal management requirements given the operational temperature limits. Verify power supply stability within the specified 4.5 V to 5.5 V range.

Sensor And Detector Interfaces Part Context

The XTR108TDD2 belongs to the XTR108 series of precision current transmitters. It shares functional similarities with the XTR108EA but differs in packaging, being offered as a bare die rather than in a QSOP-24 package. This series is designed for interfacing sensors to 4-20 mA loops with added digital intelligence. It complements other interface ICs like the XTR101 series, which offers different voltage ranges and packaging options.

Sensor And Detector Interfaces Replacement Considerations

The XTR108EA is a direct functional alternative available in a QSOP-24 package. Verify pinout compatibility and electrical specifications before substitution. Note that the XTR108EA is also subject to long delivery times or discontinuation risks. No other public substitute part numbers are confirmed.
