UDA1334A I2S Stereo DAC Module with Analog Stereo Output for Arduino and Raspberry Pi

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The UDA1334A is a compact I2S DAC module that converts digital audio into a high-quality analog stereo signal. It supports 3.3 V to 5 V logic levels and is compatible with a wide range of microcontrollers and single-board computers, including Arduino, ESP32, STM32, and Raspberry Pi.

Its built-in PLL allows operation with I2S interfaces that do not provide a Master Clock, making it especially suitable for Raspberry Pi. For standard operation, only the Data In, Word Select, and Bit Clock signals need to be connected.

The module supports standard I2S as well as left-justified 16-bit, 20-bit, and 24-bit audio formats. The analog output is line level and is intended for connection to an external audio amplifier, powered speakers, or other audio equipment. A dedicated mute input and an optional de-emphasis filter are also provided.
