Procurement Notes

Verify the manufacturer origin as Sanyo or its successor entities due to corporate restructuring. Confirm the specific suffix 'E' indicates environmental compliance if required by your supply chain standards. Ensure the package type matches your PCB footprint requirements, typically a Single In-line Package (SIP). Cross-reference with current distributor availability as legacy components may have limited stock.

Selection Notes

Select this component for applications requiring a single-channel Class AB amplifier in a compact form factor. Consider the thermal management capabilities provided by the IMST technology when designing the heatsink or board layout. Verify that the load impedance and supply voltage requirements align with the system specifications before finalizing the design.

Part Context

This part belongs to the STK404-000 series of audio power amplifier hybrid ICs. The series is characterized by the use of Sanyo's unique Insulated Metal Substrate Technology (IMST) to achieve miniaturization compared to earlier products with similar specifications.
