Performance AND Efficiency in a Class D Amplifier

The theoretical best efficiency of a linear amplifier is 78% at peak output power. At typical music reproduction levels, efficiency falls below 30%. Maxim's Class D amplifiers, such as the MAX9700 featured below, deliver efficiencies > 80% under the same conditions.

These Class D amplifiers exhibit Class AB performance using an advanced closed-loop error correction circuit to achieve the highest possible THD+N and PSRR performance.
