Description:

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 stereo 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.

The module is delivered fully assembled and tested. The delivery includes a pin header and a 2-pin terminal, which you can solder on demand. Speaker, Raspberry Pi, T-Cobbler, leads and breadboard are not included.

Feature:

3.2 W output at 10% THD, 4 Ω impedance of the speaker and 5 V power supply

2.7 - 5.5 V operating voltage

77 dB PSRR at 1 kHz

Selectable gains: 3 dB, 6 dB, 9 dB, 12 dB, 15 dB

Package includes:

1 x Audio amplifier module
