LA42031-KF-E

Audio Amplifiers Overview

The LA42031-KF-E is a monaural audio frequency power amplifier designed for television applications. It delivers 3W output at VCC = 9V, RL = 8Ω, THD = 10%, and 5W output at VCC = 11V, RL = 8Ω, THD = 10%. The device operates on a supply voltage range of 5.5V to 15V. It utilizes Class AB topology and is housed in a 13-SIP through-hole package.

Audio Amplifiers Feature Summary

• Integrated thermal protection circuitry
• Designed for direct television speaker driving

Audio Amplifiers Applications

• Television audio systems
• Mono speaker output stages
• Consumer electronics audio amplification

Audio Amplifiers Procurement Notes

Verify the specific suffix (KF-E) against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the 13-SIP package matches the target PCB footprint. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Audio Amplifiers Selection Notes

Select this component for single-channel audio applications requiring up to 5W output into an 8-ohm load. It is suitable for designs operating within a 5.5V to 15V supply range. Consider the through-hole SIP package for prototyping or legacy board designs where surface-mount options are not feasible.

Audio Amplifiers Part Context

This part belongs to the Sanyo (now Panasonic Semiconductor) LA42031 series of audio power amplifiers. The series is characterized by its use in consumer television sets. The KF-E suffix typically denotes a specific packaging and environmental compliance variant within the broader LA42031 family.

Audio Amplifiers Replacement Considerations

Check for LA42031 variants with different suffixes from Panasonic/Sanyo. Verify pin-to-pin compatibility before substitution. No direct cross-brand equivalents are confirmed in public documentation.
