MAX98357A Miniature Auditory Amplifier Module Amplifier Board with Bridge Tied Load Output 5V Enhances Sound

Features: Experience powerful Auditory amplification with the MAX98357A module, delivering up to 3.2W output at 4Ω impedance, for enhancing sound in setups. This amplifier features I2S digital auditory input, operates efficiently between 2.7V 5.5Vdc, and offers selectable setting from 3dB to 15dB for tailored Auditory performances. Perfect for adding amplifier sound, I2s sampling rate (not to be confused with I2c), in the digital sound protocol used to pass Auditory data on a circuit board. Inside the microed chip is a Class D controller capable of running between 2.7V and 5.5Vdc. Because the amplifier is class D, it is very efficient, for portablely and battery-powered projects. With Heat and overcurrent protections. The Auditory inputs I2s standard and can be used with either 3.30V or 5V logical data. By defaulted, the amplifier will give you 9dB. The pin can be set to 3db, 6db, 9db, 12db or 15db by directly connecting a pull-up or pull-down resistors or wiring.

Specifications: Model: MAX98357A Output Power: 3.2W at 4Ω ; 1.8W at 8Ω Power :With 5V power supply PSRR:77dB typical @ 1kHz I2s Sample rates from 8kHz to 96kHz Five-pin selectable: 3db, 6db, 9db, 12db, 15db Size：about 1.9x1.8cm/0.75x0.71in
