Working Principles

The CS42426-DQZR/C1 operates by receiving analog audio signals through its input channels. These signals are then converted into digital format using high-resolution ADCs (Analog-to-Digital Converters). The digital audio data is processed using the built-in DSP, allowing for various audio enhancements and effects.

The processed digital audio is then converted back to analog format using high-performance DACs (Digital-to-Analog Converters) and sent to the output channels. The device also supports digital audio input/output through its digital interface pins, enabling seamless integration with other digital audio systems.
