APA2057A Datasheet 2.4w Stereo Audio Power Amplifier

Manufacturer: Anpec Electronics Coropration

Overview: APA2057A 2.4W Stereo Audio Power Amplifier (with Gain Setting) & Capfree Headphone.

General Description

The APA2057A is a monolithic integrated circuit, which combines a stereo power amplifier and a stereo output capacitor-less headphone amplifier.

The stereo power amplifier provides 19-steps gain setting for flexible application.

The headphone amplifier is ground-reference output, and doesn’t need the output capacitors for DC blocking.
