These projects are staples for beginners and intermediate DIYers: 1. LM386 Low-Voltage Audio Amplifier

In Bridge mode, the two internal amplifiers of the TDA2005 receive inverted versions of the same input signal. The speaker is connected directly between the two amplifier outputs rather than between an output and ground. This configuration eliminates the need for large, expensive output coupling capacitors and quadruples the theoretical output power compared to a single-ended design.
