Nowadays, class D amplifiers are very popular. They are relatively easy to build, have high energy efficiency, which also allows them to be powered from portable sources, and at the same time have very good parameters, incomparable to those from a dozen or so years ago. Here is the design of an amplifier based on the MAX9768 chip. It is a mono amplifier that can be used, for example, to build an active speaker system.
Recommendations: class D amplifier with good parameters, which can be useful in many audio constructions: from home or car sound system to active loudspeaker sets.

Basic information:

• 5 ... 14 V DC power supply.
• 10W output power with 8V load and 14V power supply.
• work with 8V or 4V load.
• energy efficiency of about 87%.
• built-in voltage controlled voltage regulator.
• the ability to combine into multichannel, synchronized sets of amplifiers.
• for loudspeaker cables up to 1m, there is no need to use output chokes.
• short-circuit and thermal protection.
• dimensions 26 x 47 x 15mm

The set includes a printed circuit board, a set of elements and documentation.
