XTR108EA

Sensor And Detector Interfaces Overview

The XTR108EA is a smart, programmable two-wire current transmitter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum operating supply current of 500 uA. The device accepts a voltage input with an input bias current of 50 pA. It generates a standard 4 mA to 20 mA output current loop. Additionally, it provides a voltage output ranging from 500 mV to 4.5 V. The component supports Serial, 2-Wire, and SPI interface types for configuration. It is housed in a QSOP-24 package designed for surface mount installation. The operational temperature range spans from -40 C to +85 C.

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix EA against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure compatibility with QSOP-24 footprints during PCB layout. Confirm humidity sensitivity handling requirements if the component is exposed to moisture prior to soldering. Validate that the design accommodates the specified 4.5 V to 5.5 V supply voltage constraints.

Sensor And Detector Interfaces Selection Notes

Select this component when a low-power, two-wire solution with digital programmability is required. Compare input bias current specifications against other models if high-impedance sources are used. Verify that the QSOP-24 package dimensions fit the mechanical constraints of the target enclosure. Ensure the application environment remains within the -40 C to +85 C operating temperature range.

Sensor And Detector Interfaces Part Context

The XTR108EA belongs to the XTR108 series of smart transmitters from Texas Instruments. This family focuses on integrating signal conditioning and transmission in a single package. The EA suffix typically denotes a specific thermal grade or packaging variant within the broader product line. It serves as a bridge between analog sensors and digital control systems.

Sensor And Detector Interfaces Replacement Considerations

Consult the Texas Instruments XTR108 datasheet for officially listed alternative part numbers. Verify pin-to-pin compatibility before substituting any components. Ensure that any replacement maintains the same QSOP-24 package and electrical characteristics.
