INA121UA/2K5G4

Overview

The INA121UA/2K5G4 is a low-power instrumentation amplifier manufactured by Texas Instruments. It features FET-input stages to ensure high input impedance and low bias current. The device operates within a supply voltage range of 4.5V to 36V or ±2.25V to ±18V. Key electrical parameters include a gain bandwidth product of 0.6MHz, a slew rate of 0.7V/us, and an input offset voltage maximum of 2000uV. It is housed in an 8-pin SOIC package.

Feature Summary

FET-input architecture for high input impedance
Low power consumption design
Wide single or dual supply voltage operation

Applications

Precision sensor signal conditioning
Medical instrumentation front-ends
Industrial process control systems

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the '2K5' designation corresponds to the standard reel packaging quantity of 2500 units. Ensure the manufacturer source is explicitly Texas Instruments or its authorized Burr-Brown lineage records to validate authenticity.

Selection Notes

Select this component when high input impedance and low power are required simultaneously. The FET input stage minimizes loading effects on high-impedance sources. Verify that the 0.6MHz bandwidth meets the signal frequency requirements. Check that the 2000uV offset voltage specification aligns with the system's precision needs.

Part Context

This part belongs to the INA121 family of instrumentation amplifiers. The UA suffix denotes the plastic small-outline (SOIC) package type. The /2K5 indicates tape and reel packaging. The G4 suffix typically signifies environmental compliance features such as lead-free terminals and RoHS adherence, consistent with Texas Instruments product coding standards.

Replacement Considerations

INA121UA: Standard non-reel version of the same amplifier. INA121UAE4: Lead-free variant with equivalent electrical characteristics. INA121UA/2K5: Identical functional device in tape and reel packaging.
