Anpec Electronics APA2011
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. APA2011 provides an Dynamic-RangeControl (DRC) function, and this function can low down the dynamic range for large input signal.| Part No. | APA2011 |

GENERAL DESCRIPTION
Besides, the gain can be low down by external input resistance. APA2011 can provide maximun 15dB gain control. APA2011A can provide maximum 15dB gain decrease for non-clipping function, and this function can avoid output signal clipping. High PSRR and differential architecture provide increased immunity to noise and RF rectification. In addition to these features, a fast start-up time and small package size make the APA2011/2011A an ideal choice for portable devices. The APA2011/2011A is capable of driving 1.6W at 5V or 0.8W at 3.6V into 8Ω. It is also capable of driving 4Ω.
