Additional Details:

The W56964DYX typically operates from a 3.3V power supply and is available in a small form factor package. It supports various audio sampling rates, such as 8 kHz, 16 kHz, 32 kHz, and 48 kHz. The integrated microphone amplifier provides adjustable gain, allowing it to accommodate different microphone sensitivities. The I2S/PCM digital audio interface enables easy connection to digital audio processors and codecs. The codec also incorporates power-saving features, such as power-down modes, to minimize energy consumption when idle. This device is commonly used in applications where a balance of high-quality audio and low power consumption is required. The detailed specifications, including THD+N, SNR, and dynamic range, can be found in the product datasheet.
