The component operates with an input voltage range of 3 V to 4.5 V and features a maximum power dissipation of 5.5 W. It utilizes SMD/SMT installation style and is housed in a VCT-16 package. The device supports a minimum operating temperature of -30 C and a maximum of +75 C.
Feature Summary
- Dual-channel stereo audio amplification capability
- Low voltage operation suitable for portable devices
- Integrated thermal protection via specified power dissipation limits
Applications
- Portable audio players
- Mobile phone speaker systems
- Small form-factor stereo audio equipment
Procurement Notes
Verify the specific suffix and revision level against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm that the VCT-16 package dimensions match the PCB footprint exactly. Check for any recent product change notifications regarding material composition or manufacturing site changes before finalizing procurement orders.
Selection Notes
Select this component when a compact, low-voltage stereo amplifier solution is required for battery-powered devices. Ensure the application voltage stays within the 3 V to 4.5 V range to maintain optimal performance. Consider the thermal management capabilities given the 5.5 W power dissipation rating and the small VCT-16 package size for heat dissipation efficiency.
Part Context
The LA4262-E belongs to onsemi's portfolio of linear ICs focused on audio amplification. It serves as a specialized solution for consumer electronics requiring high-quality sound output in minimal space. The part is distinct from general-purpose operational amplifiers due to its optimized architecture for driving speakers directly.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility and electrical specifications with alternative manufacturers if sourcing constraints require substitution.
