The CRY573 facilitates the conversion of PDM and I2S signals to analog output with software-controlled switching. It offers adjustable sampling rates ranging from 8kHz to 48kHz(available only in PDM mode) and allows for fine-tuning of left and right channel gains.
Connected via USB, the CRY573 appears as a virtual serial port on your PC, enabling straightforward configuration adjustments through this interface.
