LA4425AN-D-E

Audio Amplifiers Overview

The LA4425AN-D-E is a Class-AB mono audio power amplifier manufactured by onsemi, designed for car radio and stereo applications. It delivers 5W output into a 4-ohm load with a total harmonic distortion plus noise of 0.1%. The device operates within a supply voltage range of 5V to 16V and draws a typical quiescent current of 65mA. It features a SIP-5H (TO-126 type) through-hole package, enabling minimal external component requirements. The operational temperature range spans from -30°C to +80°C.

Audio Amplifiers Feature Summary

• Class-AB topology optimized for high-fidelity audio reproduction
• Minimal external component count requiring only input and output coupling capacitors
• Integrated thermal protection mechanisms for reliable operation

Audio Amplifiers Applications

• Car radio systems
• Car stereo amplifiers
• Portable audio devices

Audio Amplifiers Procurement Notes

Verify the specific suffix 'D-E' against the manufacturer's latest datasheet to confirm pinout compatibility and environmental compliance status. Confirm that the SIP-5H package dimensions match your PCB footprint requirements. Check for end-of-life or obsolescence notices as availability may be restricted. Ensure the operating voltage range aligns with your system's power supply rails before integration.

Audio Amplifiers Selection Notes

Select this component when a single-channel, high-power solution is required for automotive audio environments. The SIP-5H package facilitates easy through-hole mounting for prototyping or low-volume production. Consider the 5W output capability relative to the 4-ohm speaker impedance to ensure adequate headroom. Evaluate the thermal performance under maximum load conditions given the limited package surface area.

Audio Amplifiers Part Context

This part belongs to the LA4425A series of power amplifiers from onsemi. The series is characterized by its ability to deliver significant power with very few external components, making it suitable for space-constrained automotive audio designs. The LA4425AN-D-E variant specifically denotes the through-hole SIP-5H package configuration.
