General Description

The MAX9736A/B/D Class D amplifiers provide high performance, thermally efficient amplifier solutions. The MAX9736A delivers 2 x 15W into 8Ω loads, or 1 x 30W into a 4Ω load. The MAX9736B/D deliver 2 x 6W into 8Ω loads or 1 x 12W into a 4Ω load.

These devices operate from 8V to 28V and provide a high PSRR, eliminating the need for a regulated power supply. The MAX9736 offers up to 88 efficiency at 12V supply.

Pin-selectable modulation schemes select between filterless modulation and classic PWM modulation. Filterless modulation allows the MAX9736 to pass CE EMI limits with 1m cables using only a low-cost ferrite bead and capacitor on each output. Classic PWM modulation is optimized for best audio performance when using a full LC filter.
