2X15W Class-D Stereo Power Amplifier Kit User's Guide
Overview
This is a Class-D audio amplifier kit designed to make use of the TPA3122D2 power
amplifier IC. Completing this kit, you will have a fully functional, dual-channel audio amplifier.
This amplifier is capable of delivering up to 15W per channel (8Ω at 28V) and can be
powered by a wide range of 10V to 30V. Gain can be selected via a 2-slide switch from
weak(20dB), low(26dB), medium(32dB) or high(36dB). The efficiency of TPA3122D2
eliminates the need for an external heat sink when playing music. All components are
through-hole and easy to be soldered on the PCB. This kit includes:
