Description
General part information
MAX9741 Series
The MAX9741 stereo Class D audio power amplifier provides Class AB amplifier performance with Class D efficiency, conserving board space and eliminating the need for a bulky heatsink. Using a Class D architecture, the MAX9741 delivers 12W continuous output power into 8Ω loads. Modulation and switching schemes render the traditional Class D EMI suppression output filter unnecessary.The MAX9741 offers two modulation schemes: a fixed-frequency mode (FFM), and a spread-spectrum mode (SSM) that reduces EMI-radiated emissions due to the modulation frequency. The device utilizes a fully differential architecture, a full bridged output, and offers comprehensive click-and-pop suppression.The MAX9741 features high 80dB PSRR, low 0.07% THD+N, and SNR in excess of 100dB. Short-circuit and thermal-overload protection prevent the device from being damaged during a fault condition. The MAX9741 is available in a 56-pin TQFN (8mm x 8mm x 0.8mm) package. The MAX9741 is specified over the extended -40°C to +85°C temperature range.ApplicationsAutomotiveDesktop PCsLCD MonitorsLCD ProjectorsLCD TVs
