D Class Audio circuit 50w x 2

Product Details

A Class-D audio circuit rated at 50W × 2 is a highly efficient stereo amplifier design capable of delivering strong, clean sound while generating minimal heat. Class-D technology works by using high-frequency switching rather than linear amplification, resulting in efficiencies above 85–90%, which allows the circuit to remain cool and compact even at higher output levels. A typical 50W × 2 Class-D amplifier includes a stereo input stage, PWM modulation section, output LC filters, and speaker protection features. Many designs use popular ICs such as the TPA3116D2, IRS2092, or similar dual-channel drivers. These amplifiers often operate from a 12–24V DC supply and are ideal for home audio systems, bookshelf speakers, DIY projects, or portable sound applications. With proper filtering and layout, they offer low distortion, high dynamic range, and excellent energy efficiency.
