Procurement Notes
Verify the specific suffix 'UA' corresponds to the 8-SOIC package variant when ordering. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the selected distributor provides genuine Texas Instruments components to maintain performance integrity.
Selection Notes
Select this component for applications requiring low power consumption alongside high precision. The 8-SOIC package suits surface-mount designs with space constraints. Consider the 200 kHz bandwidth limit for high-speed signal processing needs. Verify that the required gain range fits within the 5 V/V to 10,000 V/V specification.
Part Context
The INA126 belongs to the INAx126 family of micropower instrumentation amplifiers. This series utilizes a dual op-amp design to achieve low static current while maintaining excellent common-mode rejection. The family includes single and dual versions available in various packages such as PDIP, SOIC, and SSOP.
