2 Ч10 W Filterless Class-D Stereo Audio Amplifier SSM3302
load or with 82% efficiency at 10 W into 4 from a 12 V supply, and it has an SNR of >98 dB.

Spread spectrum pulse density modulation (PDM) is used to provide lower EMI radiated emissions compared with other Class-D architectures. The SSM3302 includes an optional modulation select pi
