Pam8610 IC is 10 watts @ 8 ohms (15 watts @ 4 ohms small heat sink require) stereo class d amplifier with very high efficiency over 90% and the amplifier works well without any heatsink at full power!!! .The amplifier board is very low cost ( around 1 $) but deliver 10 watts @ 8 ohms power from 13 volts power supply.
As you can see in my video that the amp board require only one 100 uf electrolytic capacitor for supply decoupling to eliminate hum from switching power supply(some ic amplifier require 1000 uf to eliminate hum from the power supply).
Sound testing:The amplifier sound good with good bass respond good bass impact and well control (kick bass very good). High frequency clean, impact well and flat but lack transparent. Singer vocal is clean but not transparent. The sound stage is wide but space between instrument not precise. pam 8610 amp board is the quiet amp with very less hiss noise (5 cm away from tweeter to my ear :) which is not a big problem at all and the amp do not oscillate with 1.5 meters speaker wire, not like some class d board amp.
PAM 8610 specificationPower Range: DC 7.5V-15V ( can power the amp from car and motorcycle batteries)
Recommended voltage: DC 12V(3A)
Output Power: 10W x 2(8Ω) 15Wx2(4Ω)
Frequency Response: 20HZ-30KHZ(-1 db)
queinsent Current: 20 mah (DC12V)
SNR: - 90 dbs
See sound test with JVC loudspeaker.
I use Olympus e-pm2 camera built-in stereo microphone to record sound and video resolution is @1080p
The amplifier board is very tiny 1"x1"dimension.
If you want low-cost but high-quality board amplifier TA 2024 class t amplifier is a good choice for you. Find TA2024 amplifier here
