APA2010A - ANPEC

APA2010A 3W Mono Class-D Audio Power Amplifier

The APA2010/2010A is a mono, filter-free Class-D audio amplifier available in a WLCSP-9 and TDFN3x3-8 packages. The gain can be set by an external input resistance. High PSRR and differential architecture provide increased immunity to noise and RF rectification. In addition to these features, a fast startup time and small package size make the APA2010/2010A .
