MAX98390
Description
The MAX98390 is a high-efficiency mono Class-D DSM smart amplifier that features an integrated boost converter, integrated Dynamic Speaker Management TM, and FET scaling for higher-efficiency at low output power.
The maximum boost converter output voltage is programmable from 6.5V to 10V in 0.125V increments from a battery voltage as low as 2.65V. The boost converter supports bypass mode for lower quiescent current and improved mid-power efficiency as well as envelope tracking which automatically adjusts the output voltage for maximum efficiency. The boosted supply efficiently delivers up to 6.2W at 10% THD+N into a 4Ω load.
Integrated IV sense and Dynamic Speaker Management allows louder, fuller audio while protecting the speaker against damage and improving sound quality.
The PCM interface supports I2S, left-justified, and 16-channel TDM formats as a slave or master device with I2C control. Either BCLK or MCLK can be used as the internal clock source providing system...
