This is a 2x50W audio amplifier which integrates TI’s TPA3116 as the driver. It has perfect class-D architecture and each channel has 50W power output. This board can be powered by any DC12V-24V power supply. It can be used to drive any 4Ω or 8Ω passive speakers. There are a ON/OFF switch and a volume knob on the front panel. It's very easy to use.
Specification:
TA = 20℃, fIN = 1 kHz sine wave, RL = 4Ω. (Unless otherwise stated)
