INA106U/2K5

Overview

The INA106U/2K5 is a precision differential amplifier manufactured by Texas Instruments, featuring a fixed gain of ten. It operates within a supply voltage range of 7.5 V to 36 V and supports single-supply configurations. The device utilizes an 8-SOIC surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C. Designed for high accuracy, it integrates laser-trimmed resistors to ensure precise signal conditioning without external components.

Feature Summary

• Precision fixed gain of ten with factory-trimmed internal resistors
• High common-mode rejection ratio for accurate differential signal amplification
• Single-supply operation capability simplifying system power design

Applications

• Industrial process control sensor signal conditioning
• Medical instrumentation requiring high-precision differential measurements
• Strain gauge and bridge sensor interface circuits
• Data acquisition systems needing isolated input stages

Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with existing board layouts regarding the SOIC-8 footprint and thermal requirements. Cross-reference the latest datasheet revision for any updates on recommended operating conditions or handling precautions.

Selection Notes

Select this component when a stable, high-accuracy gain of ten is required for differential signals. Consider its wide supply voltage range and single-supply operation for flexible power architectures. Evaluate the trade-off between its fixed gain and adjustable alternatives if variable amplification is necessary for the application.

Part Context

This part belongs to the INA10x series of precision differential amplifiers from Texas Instruments. These devices are designed to replace discrete resistor networks, offering superior matching and temperature stability. The series provides a robust solution for applications demanding high common-mode rejection and low drift in compact surface-mount packages.

Replacement Considerations

Official substitutes include the INA105U/2K5 for unity-gain applications and the INA107U/2K5 for a gain of one hundred. Verify pinout compatibility and electrical parameter alignment before substitution. Consult the manufacturer's cross-reference guide for validated equivalent parts ensuring functional parity.
