Product Overview
MAX9744ETH+ is a 20W stereo class D speaker amplifier with volume control. It 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 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. Applications include flat-panel televisions, PC speaker systems, multimedia docking stations.
- Wide 4.5V to 14V power-supply voltage range
- Filterless 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)
- Integrated click-and-pop suppression, low-power shutdown mode
- Short-circuit and thermal-overload protection
- Power-supply rejection ratio is 83dB typ at PVDD=4.5V to 14V
- Efficiency is 93% typ at POUT=10W, fIN=1KHz, 8ohm load
- 44 TQFN-EP package
- Temperature range from -40°C to +85°C
