Audio Power Amplifiers

Within our broad portfolio of audio power amplifiers, you will find end-to-end digital solutions, as well as classic analog amps, in class AB or D, with output power ranging from 1 to 250 watts.

A growing line of lower power audio solutions (< 5.5 V), are targeted for speaker and headphone outputs on mobile phones, PDAs, and laptop PCs

For the higher output power range, ST offers its latest generation of digital audio power amplifiers, based on Apogee's Direct Digital Amplification (DDX®) technology. Combining all-digital and high efficiency Direct Digital Amplification, ST's audio power solutions can be used in a wide range of consumer audio products.
