MAX9708ETN Filterless Spread Spectrum Mono/Stereo Class D Amplifier
Price in Sri Lanka

The MAX9708 mono/stereo, Class D audio power amplifier delivers up to 2 x 21W into an 8Ω stereo mode and 1 x 42W into a 4Ω load in mono mode while offering up to 87?ficiency. The MAX9708 provides Class AB amplifier performance with the benefits of Class D efficiency, eliminating the need for a bulky heatsink and conserving power. The MAX9708 operates from a single +10V to +18V supply, driving the load in a BTL configuration.

The MAX9708 offers two modulation schemes: a fixedfrequency modulation (FFM) mode, and a spread-spectrum modulation (SSM) mode that reduces EMI-radiated emissions. The MAX9708 can be synchronized to an external clock from 600kHz to 1.2MHz. A synchronized output allows multiple units to be cascaded in the system.
