Description
The DAC stereodecoder's module to communicate through theI2Sinterface. Built-inclass D amplifiercan provide up to3.2 W of power to the speakers or headphones with impedance up to4 Ω. Itprocesses the digital signal from computer/microcomputer to analog, which are processed through the speakers. It is also compatible with devices such asRaspberry PiorArduino. The module can be supplied with voltagefrom 2.5 V to 5.5 Vand a maximum current consumption is 1.5 A.
Pins
| PIN | Description |
|---|---|
| LRCLK | Frame Clock - informs the amplifier about input channel (left/right or stereo) |
| BCLK | Bit Clock - tells the amplifier when to read the data from the pins data. |
| DIN | Data in - the input data. |
| GAIN | The gain setting +3/6/9/12/15 dB (by default is +9 dB) |
| SD | Shutdown and channel select |
| GND | The mass of the system. |
| 2.5-5.5 V |
Powered from 2.5 V to 5 V. |
