19-4327; Rev 0; 10/08 KIT ATION EVALU E L B AVAILA Mono 7W Class D Amplifier General Description Features - 8V to 28V Supply Voltage Range - Spread-Spectrum Modulation Enables Low-EMI Solution - Passes EMI Limit with Up to 1m of Speaker Cable - High 80d B PSRR - Up to 88% Efficiency Eliminates Heatsink - Thermal and Output Current Protection - < 1µA Shutdown Mode - Click-and-Pop Suppression - < 10ms Turn-On Time - Space-Saving, 4mm x 4mm x 0.8mm, 24-Pin TQFN Package 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 80d B 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. prehensive 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.
