How to Design and Build an Amplifier With the TDA2050

PCBs for this project are available here.  Note: This guide will also work with the TDA2030 as long as you keep the supply voltage below ±18 V. The TDA2050 is a great sounding chip amplifier with lots of power. In this tutorial, I’ll walk you through the amplifier design process as I build a 25 Watt stereo amplifier with the TDA2050. First, I’ll show you how to calculate the voltage and current requirements of your power supply, and show you how find a properly sized heat sink. Then, I’ll show you how to find the right values for all of the components in the circuit. I’ll also...
