Description
Module decoder stereo DAC based on UDA1334A, it communicates using the classic default I2S interface or 16-bit, 20-bit or 24-bit. It is supplied with the voltage from 3.3 V to 5 V, making it compatible with devices such as Raspberry Pi or Arduino. Characterized by the absence of damping and distortion. On board is a 3.5 mm Jack to connect e.g. headphones.
Pins
The module communicates using the I2S interface. It also has pins, such as Word Select (left / right clock) Bit Clock Lines, pin Mute and filter de-emphasis. Detailed information is available in the user manual provided by the manufacturer.
| PIN | Description |
|---|---|
| VIN | Powered by 3.3 V to 5 V. |
| GND | The mass of the system. |
| WSEL | Word Select or Left / Right Clock - informates the DAC when the data is for the left channel and when for the right channel. |
| DIN | Data in - the input of data. |
| BCLK. | Bit Clock - tells the amplifier when to read the data from the data pin. |
| MCLK |
This system does not need MCLK, if the audio device has a Jack, you should leave them unconnected. |
| AGND |
Clean, analog ground. It can be used as an analog reference to get a more clean signal. |
| SCLK |
Clock line. |
| Mute |
Set to high state mutes the output signal. |
| DEEM |
It can be used to add a filter de-emphasis. |
| PLL |
Low for the Arduino by default. It can be set to high state to change video frequency on PAL or NTSC. |
| SF0/SF1 |
Is used to change the I2S input data format, low state by default (details on the back of the board). |
