Description:
I2S Digital Audio Amplifier Board for Raspberry Pi. receives digital audio through the I2S interface, converts it to an analog output signal, and amplifies it for direct speaker connection. It combines an I2S D/A converter and an audio amplifier on one board. The small stereo amplifier module is powerful, delivering up to 3.2 W on 4 Ω impedance speakers. the class D amplifier can be operated from 2.7 V to 5.5 V. The amplifier can also be used as an audio amplifier. Due to the amplifier's rate, the module is particularly suitable for mobile and battery-powered projects.The I2S audio input supports both 3.3 V and 5 V levels. The gain can be set to the following values using the gain input: 3 dB, 6 dB, 9 dB, 12 dB and 15 dB.
By default, the stereo signal (L + R) is mixed to form the output signal. Resistors can be used to change the behavior so that only L or R is output.
Characteristics: 
Output 3.2 W at 10% THD, speaker impedance 4 Ω, power supply 5 V
2.7-5.5 V operating voltage
77 dB PSRR at 1 kHz
Selectable Gain: 3 dB, 6 dB, 9 dB, 12 dB, 15 dB
Product Size: 18.00x18.00x3.00mm/0.71x0.71x0.12inch
