APA2012 - 3W Mono Class-D Audio Power Amplifier

Description

The APA2012 is a mono, filter-free Class-D audio amplifier available in a WLCSP package.

The gain can be setting by external input resistance.

High PSRR and differential architecture provide increased immunity to noise and RF rectification.
