APA2011 - ANPEC

APA2011 2.8W Mono Class D Audio Power Amplifier

The APA2011/2011A is a mono, filter-free Class-D audio amplifier available in WLCSP1.5x1.5-9 or TDFN3x3-8 package. The default gains without the external input resistor is 27dB. Besides, the gain can be low down by external input resistance. APA2011 provides an Dynamic-RangeControl (DRC) function, and this function can low down the dynamic range for large in.
