MAX9744ETH+T

The MAX9744ETH+T is a 20W stereo class D speaker amplifier with volume control in 44 pin TQFN package. This 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. It features a 64-step dual-mode (analogue or digital), programmable volume control and mute function. It 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. It is used in flat-panel televisions, PC speaker systems and multimedia docking stations.

• Supply voltage range is 4.5V to 14V
• Operating temperature range from -40°C to 85°C
• Filter less spread-spectrum modulation lowers radiated RF emissions from speaker cables
• 20W stereo output (4ohm, VDD = 12V, THD+N = 10%)
• Integrated volume control (I2C or analogue)
• Low 0.04% THD+N, high 75dB PSRR & high 93% efficiency
• Low-power shutdown mode
• Short circuit and thermal overload protection
