MAX98357A BGA 2.8 I2S 3W Class D Mini Mono Amplifier Module
The I2S digital audio amplifier board is suitable for Raspberry Pi. Accepts digital audio through the I2S interface, converts it to an analog output signal and amplifies it to allow direct speaker connection. It combines an I2S D / A converter with an audio amplifier on one board.
The small Mono amplifier module is surprisingly powerful and delivers up to 3.2W on 4Ω impedance speakers. The class D amplifier can be operated with a voltage of 2.7 V - 5.5 V. Due to the high efficiency of the amplifier, the module is particularly suitable for mobile and battery-powered projects.
The I2S audio input supports 3.3V and 5V levels. The gain can be set to the following values using the gain input: 3dB, 6dB, 9dB, 12dB and 15dB By default, the stereo signals (L + R) are mixed to form an output signal. The behavior can be changed using a resistor so that only L or R is output.
