Additional Details:

The CS4344-CZZR/DZZR features a multi-bit delta-sigma modulator architecture, providing excellent linearity and dynamic range. The integrated digital interpolation filter reduces the need for external filtering components. The differential analog outputs minimize noise and distortion. The I2S serial audio interface simplifies connectivity with digital audio sources. The device typically operates from a single 3.3V or 5V power supply. It offers a signal-to-noise ratio (SNR) of typically 105 dB and a total harmonic distortion plus noise (THD+N) of -95 dB. The CS4344 is available in a small QFN package, making it suitable for space-constrained applications. This DAC is designed to deliver high-quality audio performance in a variety of consumer and professional audio products.
