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 package and is specified over the -40°C to +85°C temperature range.
