LA4278-E

Audio Amplifiers Overview

The LA4278-E is a dual-channel audio frequency power amplifier manufactured by Sanyo Semicon Device. Designed for home stereo and television applications, this component delivers 10 watts of output power per channel under standard test conditions (VCC = 25 V, RL = 8 Ω, f = 1 kHz). It operates within a wide voltage range of 10 V to 32 V and incorporates built-in protection mechanisms against thermal shutdown and overvoltage abnormalities.

Audio Amplifiers Feature Summary

• Dual-channel architecture providing independent amplification for stereo applications
• Integrated protection circuitry including thermal shutdown and overvoltage safeguards
• Minimal external component requirement with no bootstrap capacitor needed
• Low pop noise performance during power switch-on and switch-off transitions

Audio Amplifiers Applications

• Home stereo systems
• Television audio circuits
• Tape recorder radio units

Audio Amplifiers Procurement Notes

Verify the manufacturer designation as Sanyo Semicon Device or its successor entities when sourcing. Confirm that the specific suffix matches the required operational characteristics. Ensure compatibility with the intended supply voltage range and load impedance specifications before integration into the final design.

Audio Amplifiers Selection Notes

Select this component for applications requiring high power output with low distortion in consumer electronics. The absence of a bootstrap capacitor simplifies the circuit layout. Verify that the operating environment remains within the specified temperature limits to ensure the reliability of the built-in thermal protection features.
