INA106U

Overview

The INA106U is a precision fixed-gain differential amplifier manufactured by Texas Instruments. It provides a precise gain of 10 V/V with a gain error of only 0.025%. The device features a gain-bandwidth product of 5 MHz and a slew rate of 3 V/us. It operates on a single power supply ranging from 10 V to 36 V, consuming 1.5 mA of operating current. Key electrical specifications include an input offset voltage of 50 uV and a common-mode rejection ratio of 86 dB. The component is housed in an 8-pin SOIC package and supports surface mount installation.

Feature Summary

• Precision fixed gain of 10 V/V
• Low gain error of 0.025%
• High common-mode rejection ratio

Applications

• Industrial process control signal conditioning
• Medical instrumentation data acquisition
• Test and measurement equipment front-ends
• Strain gauge and bridge sensor interfaces

Procurement Notes

Verify the specific ordering suffix for packaging options such as tape and reel quantities. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Ensure the selected variant matches the required temperature range and package type for the target application design.

Selection Notes

Select the INA106U when a fixed gain of 10 is required without external resistor trimming. Compare against adjustable gain amplifiers if variable gain flexibility is needed. Consider the 5 MHz bandwidth and 3 V/us slew rate for high-speed signal processing requirements within the specified supply voltage range.

Part Context

The INA106U belongs to the INA106 series of precision differential amplifiers from Texas Instruments. This series is designed for applications requiring accurate signal amplification with minimal external component count. The U suffix indicates the SOIC surface-mount package variant, distinguishing it from other package options like the KP through-hole version.

Replacement Considerations

Official substitute part numbers are not explicitly confirmed in the provided source material. Verify compatibility with alternative differential amplifiers based on pinout, gain accuracy, and electrical specifications before implementation.
