The MAX9742 stereo Class D audio power amplifier delivers up to 2 x 16W into 4Ω loads. The MAX9742 features high-power efficiency (92% with 8Ω loads), eliminating the need for a bulky heatsink and conserving power. The MAX9742 operates from a 20V to 40V single supply or a ±10V to ±20V dual supply. Features include fully differential inputs, comprehensive click-and-pop suppression, low-power shutdown mode, and an externally adjustable gain. Short-circuit and thermal-overload protection prevent the device from being damaged during a fault condition.
The MAX9742 is available in a thermally efficient 36-pin TQFN (6mm x 6mm x 0.8mm) package and is specified over the -40°C to +85°C extended temperature range.
