MAX9712 Datasheet | Maxim Integrated

19-2917; Rev 1; 1/04 500mW, Low EMI, Filterless, Class D Audio Amplifier General 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. .. The MAX9712 offers two modulation schemes: a fixedfrequency (FFM) mode, and a spread-spectrum (SSM) mode that reduces EMI-radiated emissions due to the modulation frequency. Furthermore, the MAX9712...
