INA101KU

Overview

The INA101KU is a very high accuracy instrumentation amplifier manufactured by Texas Instruments. It features a fixed gain of 10 V/V and utilizes an internal precision resistor network to eliminate the need for external gain-setting components. The device incorporates FET input stages, providing low input bias current and high input impedance. It operates within a wide supply voltage range and supports both single and dual power supplies. The component is housed in a 14-pin CDIP package.

Feature Summary

• Fixed unity-gain configuration with integrated precision resistors
• FET input stage for low bias current and high impedance
• High common-mode rejection ratio for accurate signal conditioning

Applications

• Precision data acquisition systems
• Medical instrumentation
• Industrial process control
• Strain gauge amplification

Procurement Notes

Verify the specific suffix 'KU' against the manufacturer's official datasheet to confirm pinout compatibility and package type. Ensure that the fixed gain specification meets the circuit requirements, as external adjustment is not possible. Confirm RoHS compliance status through the authorized distributor's documentation before finalizing procurement.

Selection Notes

Select this component when a fixed gain of 10 V/V is required without the complexity of external resistor matching. The FET input architecture makes it suitable for high-impedance source applications where minimal loading is critical. Consider the package constraints and thermal characteristics relative to the target PCB layout and operating environment.

Part Context

The INA101KU belongs to the INA101 series of instrumentation amplifiers from Texas Instruments. This series is designed for applications requiring high accuracy and stability. The device integrates the gain-setting network internally, simplifying the design process compared to discrete instrumentation amplifier solutions. It is part of the broader portfolio of precision analog signal chain components offered by the manufacturer.
