PRODUCT DESCRIPTION
YL2020 20W 20W D Class 12V-24V Mini Digital Power Amplifier Module is simple and mini size class D power amplifier but it has a remarkable audio power output via its dual stereo channel of 20W per channel
Schematic and Pin Description:
As you can see in the schematic it is a small PCB, easy to install, with marked terminals and convenient for soldering. You just need to solder everything where it belongs.
If you do not use MUTE, connect FAULT and MUTE together – it will mute the amplifier in case of errors.
To enable MUTE, it must be connected to the positive supply voltage VCC (Smaller enough, but it is the easiest way).
The SD input is! SHUTDOWN, no need to plugin, and don’t use it as a mute either, as using it will make your speakers pound.
Package Includes:
1 x YL2020 20W 20W D Class 12V-24V Mini Digital Power Amplifier Module

Frequently Asked Questions
What supply voltage does the YL2020 amplifier require?
The YL2020 operates from 12V to 24V DC and can handle up to 4A of dynamic current. Use a stable power source rated for your speaker load to ensure consistent performance.
How do I mute or shut down the amplifier?
Pull the MUTE pin low to silence the outputs without cutting power. For minimal current draw in standby, pull the SD (shutdown) pin low; the module will enter a low-quiescent state <40mA.
Can I use this module with both 4Ω and 8Ω speakers?
Yes. The YL2020 delivers its full 20W per channel into 4Ω loads and will produce slightly lower power into 8Ω speakers while maintaining high efficiency and low distortion.
