The MAX9737 mono 7W Class D amplifier provides a

high-performance, thermally efficient amplifier solution

that offers up to 88% efficiency at a 12V supply. The

device operates from 8V to 28V and provides a high 80dB

PSRR, eliminating the need for a regulated power supply.

Filterless modulation allows the MAX9737 to pass CE

EMI limits with 1m cables using only a low-cost ferrite

bead and small-value capacitor on each output.

Comprehensive click-and-pop suppression circuitry

reduces noise on power-up/down or into and out of

shutdown or mute.

An input op amp allows the user to create a lowpass or

highpass filter, and select an optimal gain. The internal

precharge circuit ensures clickless/popless turn-on

within 10ms.

The MAX9737 is available in the 24-pin, TQFN-EP pack-

age and is specified over the -40°C to +85°C tempera-

ture range.
