Features

AI Translation
  • The MAX9744 20W 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.
  • This device features single-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 function.
  • The MAX9744 operates from a 4.5V to 14V single supply and can deliver up to 20W per channel into a 4Ω 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-circuit and thermal-overload protection prevent device damage during a fault condition.
  • The MAX9744 is available in a 44-pin thin QFN-EP (7mm x 7mm x 0.8mm) package and is specified over the extended -40℃ to +85℃ temperature range.
