HLF386 – Class AB Low-Voltage Audio Power Amplifier (DIP8) 0.7W @9V (8Ω) | 4V–12V, 0°C to +70°C | Through-Hole Package

The HLF386 (DIP8) is a Class AB low-voltage audio power amplifier designed for small power output applications such as radios, intercoms, and portable audio systems. Operating from 4V to 12V, it delivers up to 0.7W output power into an 8Ω load with low total harmonic distortion (0.2%) and a quiescent current of just 4mA.

This amplifier provides excellent stability, minimal external components, and strong noise immunity, making it ideal for low-voltage, battery-operated consumer devices.
