Audio amplifiers provide a means to amplify signals for loudspeakers, headphones or other audio equipment. The PAM8620TR is a stereo 20W Class-D audio amplifier specifically designed to maximize power efficiency without compromising audio quality. It offers an ideal solution for portable products that require stereo audio amplifications.

In terms of application field of PAM8620TR, it is widely used in PC multimedia speaker, portable radio, amplifier devices, portable device and many other applications where audio amplification is required.

In terms of its working principle, the PAM8620TR is a two-channel amplifier with dual 20W Class-D output stages. It is designed with high-efficiency power stage that is capable of running from a single 5V input power supply. The power stage design incorporates a closed-loop system with high signal-to-noise ratio performance. The amplifier also includes high-efficiency bridged output stages that provide high-performance audio amplification.

The PAM8620TR employs BTL (bridge-tied load) load modulation to ensure that the amplifier maintains a linear output response and low distortion up to the maximum 20W power output. It features built-in thermal overload protection and short circuit protection to ensure that the amplifier can operate reliably in challenging environments. The integrated DC protection circuitry further protects the amplifier from damage due to exceeding the maximum input voltage.
