MAX9700 Datasheet | Maxim Integrated

19-3030; Rev 1; 6/04 1.2W, Low-EMI, Filterless, Class D Audio Amplifier General Description The MAX9700 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 MAX9700 delivers 1.2W into an 8Ω load while offering efficiencies above 90%. A patented, low-EMI modulation scheme renders the traditional class D output filter unnecessary. The MAX9700 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 MAX9700 oscillator can be synchronized to...
