MAX9737ETG+T

The MAX9737ETG+T is a mono 7W class D amplifier in 24 pin TQFN package. It 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 need for a regulated power supply. Filter less modulation allows the IC 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 user to create a low pass or high pass filter and select an optimal gain. The internal precharge circuit ensures clickless/popless turn-on within 10ms. It is used in 2.1 notebook PCs, LCD/PDP/CRT monitors, PC surround speakers and MP3 docking stations.
