XTR108TDD1

Sensor And Detector Interfaces Overview

The XTR108TDD1 is a smart two-wire current transmitter from Texas Instruments, designed for sensor interface applications. It operates on a single supply voltage ranging from 4.5 V to 5.5 V with a typical quiescent current of 500 uA. The device accepts a voltage input and provides a standard 4 mA to 20 mA output current loop. It features an internal reference voltage and supports serial communication via SPI for programmable configuration. The component is available in a die format, suitable for integration into custom packages or modules.

Sensor And Detector Interfaces Feature Summary

• Supports two-wire loop-powered operation for simplified wiring in industrial environments
• Includes programmable gain amplifier and linearization capabilities for accurate signal conditioning
• Enables digital configuration through SPI interface for flexible setup and diagnostics

Sensor And Detector Interfaces Applications

• Industrial process control systems requiring 4-20mA transmission
• Smart sensor nodes needing integrated signal conditioning and communication
• Two-wire transmitter implementations for pressure, temperature, or flow sensors

Sensor And Detector Interfaces Procurement Notes

Verify the specific die revision and handling requirements when sourcing bare die components. Ensure proper ESD protection during assembly due to the exposed silicon nature. Confirm compatibility with your chosen packaging solution as this part is not provided in a standard commercial package. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Sensor And Detector Interfaces Selection Notes

Select the XTR108TDD1 when a compact, programmable two-wire transmitter solution is required within a custom module design. Consider the 4.5V to 5.5V supply constraint and ensure the application can accommodate the SPI interface for configuration. Compare against packaged variants like the XTR108EA if board space allows for standard surface-mount installation instead of die attachment.

Sensor And Detector Interfaces Part Context

The XTR108TDD1 belongs to the XTR108 family of smart transmitters from Texas Instruments. This series integrates precision analog front-end circuitry with digital control interfaces. The TDD1 suffix indicates a die version, distinct from the QSOP-24 packaged XTR108EA. It shares core functional specifications with other members of the XTR108 line but differs in physical form factor and integration level.
