The UDA1334A I2S Stereo DAC Module is a compact and efficient audio decoder that converts digital audio signals into analog stereo outputs. It is particularly suitable for projects involving Raspberry Pi, Arduino, and other microcontrollers with I2S audio interfaces. This module is ideal for applications requiring high-fidelity audio playback, such as audio players, embedded systems, and DIY audio projects.

Features :

• Wide Voltage Compatibility: Operates with input logic levels from 3.3V to 5V, making it compatible with a variety of microcontrollers.
• Multiple Audio Formats Support: Supports standard I2S, as well as 16-bit, 20-bit, and 24-bit left-justified data formats.
• Built-in Phase-Locked Loop (PLL): Eliminates the need for an external master clock (MCLK); the module can generate the necessary clock signals internally, simplifying integration.
• Analog Output: Provides a clean, stereo line-level output suitable for direct connection to audio amplifiers or headphones.
• Mute and De-emphasis Control: Includes pins for muting the audio output and applying a de-emphasis filter, offering additional control over the audio signal.
• Compact Form Factor: Measuring approximately 40mm x 25mm, the module is small enough for integration into space-constrained projects.
