Introduction

AI Translation

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.
