UDA1334A I2S Stereo Low Power Audio DAC Module with PLL

The UDA1334ATS is a single chip 2 channel digital-to-analog converter employing bitstream conversion techniques, including an on-board PLL. The extremely low power consumption and low voltage requirements make the device eminently suitable for use in low-voltage low-power portable digital audio equipment which incorporates a playback function. The UDA1334ATS supports the I2S-bus data format with word lengths of up to 24 bits and the LSB-justified serial data format with word lengths of 16, 20 and 24 bits. The UDA1334ATS has basic features such as de-emphasis (44.1 kHz sampling frequency, only supported in audio mode) and mute. APPLICATIONS: This audio DAC is excellently suitable for digital audio portable application, specially in applications in which an audio related system clock is not present.

Logic levels from 3.3V - 5V (a rarity), and can process multiple different formats by setting two pins high or low. The DAC will process data immediately and give you a clear analog stereo line level output.
