Here is a Class-D amp I worked on at TI that does 116W on two channels or 58W on 4 channels for a total power of 232W. Its a little pricey, but definitely pushes the industry standard in power and ...

The major plus point of Class D is that it is very energy efficient. A typical Class A design tends to be around 30% efficient. Class A/B roughly doubles that while Class D amplifiers almost triple it ...

Basically, a digital (Class D) amplifier takes an incoming analog signal and converts it into a digital representation comprised of pulse widths. Although there are a number of different design ...

An Arduino Due forms the heart of the project, ... The sound signal is passed through an LM4811 headphone amplifier for private listening, and a PAM8403 Class D audio amplifier for the built-in ...

The $379 WiiM Amp Pro is a compact, high-performance Class D streaming amplifier featuring a Texas Instruments TPA3255 chip delivering 60W per channel at 8Ω (120W at 4Ω), an ESS ES9038 Q2M DAC for ...

GaN Systems is claiming up to 96% power efficiency from a 200 + 200W (8Ω) Class-D stereo amplifier built around its gallium nitride power transistors. THD+N is under 0.03%, with further optimisation ...
