This module (PAM8610) is a 10 W (per channel) stereo Class-D audio amplifier with DC volume control which offers low THD+N (0.1%), low EMI, and good PSRR thus high-quality sound reproduction. The 32 steps DC volume control has a +32 dB to -75 dB range.
Features:

1. 10 W @ 10% THD/channel output into an 8 Ohm load at 13 V
2. low noise: -90 dB
3. over 90% efficiency
4. 32 step DC volume control from -75 dB to + 32 dB
5. shutdown/mute/fade function
6. over current, thermal and short-circuit protection
7. low THD+N
8. low quiescent current
9. pop noise suppression

Specifications:

1. supply voltage (Vdd): 7 to +15 V
2. input voltage range (Vi):
   1. mute, Vref, volume, fade: 0 to +6.0 V
   2. SD: -0.3 to Vdd
   3. RINN, RINP, LINN, LINP: -0.3 to +6.0 V
3. junction temperature range (Tj): -40 to +125 °C
4. output power @ 8 Ohm: 10 W
