CRY573 Digital Microphone Converter
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.

Product Highlights
Features
- USB interface
The CRY573 is powered and communicates via a USB interface. Please note that the USB interface has a recommended load current of ≤ 100mA. The device supports flexible switching between PDM and I2S modes, allowing users to adjust the signal sampling rate and analog output gain through the accompanying software.
Key Features
- DIP switch
The CRY573 utilizes a DIP switch to set the working voltage of the device chip, offering options of 3.3V, 3.0V, 2.8V, 2.0V, and 1.8V, with a deviation within 0.1V. This allows for precise matching of digital signals to the varying electrical levels of external devices.
- Analog signal output
Analog signal output is provided through a 3.5mm audio jack, with left and right channels corresponding directly to the digital signal’s left and right channels.
Additional Features
- PDM signal input
Supports a single PDM signal input (including both L/R channels). The software allows you to configure the clock frequency (sampling rate) for the PDM interface and adjust the gain for the left and right channels of the analog output.
- I2S signal input
Supports a single I2S signal input (standard I2S mode only), accommodating L/R channels with frame lengths of 16 to 32 bits per channel. The software allows you to adjust the gain for both the left and right channels of the analog output.
