INA106UG4

Overview

The INA106UG4 is a precision, fixed-gain differential amplifier manufactured by Texas Instruments. It provides a precise gain of 10 V/V with high common-mode rejection ratio (CMRR). The device utilizes laser-trimmed thin-film resistors to ensure accuracy and stability over temperature variations. It operates from dual power supplies, typically ranging from ±5V to ±15V, supporting single-supply operation as well. The component is housed in a standard 8-pin DIP package.

Feature Summary

• Precision fixed gain of 10 V/V achieved through internal laser trimming
• High common-mode rejection ratio for accurate signal processing
• Low input bias current and low offset voltage characteristics
• Integrated bridge excitation capability

Applications

• Strain gauge and load cell signal conditioning
• Thermocouple amplification
• Medical instrumentation front-ends
• Industrial process control sensors

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status according to the manufacturer's datasheet. Confirm the package type matches design requirements. Check for obsolescence notices or lifecycle status directly from Texas Instruments documentation before finalizing procurement plans.

Selection Notes

Select this component when a fixed gain of 10 is required without external resistor networks. It is suitable for applications demanding high CMRR and low drift. Compare against adjustable gain alternatives if flexibility is needed. Ensure supply voltage ranges match the system architecture.

Part Context

The INA106U belongs to the Burr-Brown precision amplifier family acquired by Texas Instruments. This series focuses on high-performance analog signal conditioning. The G4 suffix typically denotes environmental compliance features such as lead-free packaging and halogen-free materials, aligning with modern manufacturing standards.

Replacement Considerations

INA106UE4 is a verified equivalent part number representing the same functional specifications with potential minor packaging or compliance updates. Verify pin compatibility and electrical parameters against the official datasheet before substitution.
