Overview
The KM4212IC8 is a dual ultra-low power voltage feedback amplifier manufactured by Fairchild Semiconductor. It operates on supply voltages of +2.7V and +5V, consuming only 70µA of supply current per amplifier. The device features a 7.3MHz bandwidth and rail-to-rail output capability, designed for low-cost portable applications.
Feature Summary
- Ultra-low power consumption with 70µA supply current per amplifier
- Rail-to-rail output operation compatible with +2.7V and +5V supplies
- Dual channel configuration in a compact surface-mount package
Applications
- Portable battery-powered devices
- Active filters
- Signal conditioning circuits
Procurement Notes
Verify the manufacturer source to ensure authenticity, as Fairchild Semiconductor assets are now part of ON Semiconductor. Confirm the specific suffix IC8 corresponds to the MSOP-8 package variant. Check RoHS compliance status and verify that the component matches the original Fairchild datasheet specifications rather than generic equivalents.
Selection Notes
Select this component when ultra-low quiescent current is critical alongside moderate bandwidth requirements. It serves as a cost-effective alternative to higher-power amplifiers in space-constrained designs. Ensure the application does not require high slew rates or large signal swings beyond the rail-to-rail specification limits defined for the 2.7V to 5V operating range.
Part Context
This part belongs to the KM421x series of low-cost operational amplifiers from Fairchild Semiconductor. The series includes variants like the KM4210 and KM4211, differentiated primarily by bandwidth and current consumption. The KM4212 specifically targets applications requiring minimal power draw while maintaining basic signal integrity in single-supply systems.
Replacement Considerations
The KM4210IM8 is documented as a direct replacement option within the same family, offering similar functionality with different bandwidth characteristics. Verify pin compatibility and electrical parameter alignment before substitution.
