Class-AB Audio Amplifiers

Robustly designed, simple to design-in, and offering unmatchable sound quality, our Class AB audio amplifiers are a cost-effective, easy option that can improve your end-product value and quicken your development time.

ST offers the largest Class AB amplifier portfolio in the market, offering a output power range from a few mW to up to 100 W RMS per channel, in mono, stereo or multichannel versions. This means application coverage from mobile phones to high-end audio applications such as professional musical equipment (keyboards, amps), home theatre and hi-fi stereo systems. Added to this, our package choices reduce manufacturing and board cost via SMD or insertion packages and packaging offering excellent heat dissipation.
