20W Stereo Class D Speaker Amplifier With Volume Control

The MAX9744 20W stereo Class D Audio power amplifi- er provides Class AB Amplifier performance with Class D efficiency, conserving board space and eliminating the need for a bulky heatsink. This device features sin- gle-supply operation, adjustable gain, shutdown mode, a SYNC output, speaker mute, and industry-leading click-and-pop suppression. The MAX9744 features a 64-step dual-mode (analog or digital), programmable Volume Control and mute func- tion. The MAX9744 operates from a 4.5V to 14V single supply and CAN deliver up to 20W per channel into a 4 speaker with a 14V supply. The MAX9744 offers two modulation schemes: a fixed- frequency modulation mode that allows one of several preset switching frequencies to be selected, and a spread-spectrum modulation mode that helps to reduce EMI-radiated emissions. The MAX9744 features high 75dB PSRR, low 0.04% THD+N, and SNR in excess of 90dB. Robust short-cir- cuit and thermal-overload protection prevent device damage during a fault condition. The MAX9744 is avail- able in a 44-pin thin QFN-EP (7mm x 7mm x 0.8mm) package and is specified over the extended -40C to +85C temperature range.    By Maxim Integrated Products
