MAX9712 Description
The MAX9712 mono class D audio power amplifier provides class AB amplifier performance with class D efficiency, conserving board space, and extending battery life. Using a class D architecture, the MAX9712 delivers up to 500mW into an 8Ω load while offering efficiencies above 85%. A patented, low EMI modulation scheme renders the traditional class D output filter unnecessary.
