Working Principles

The ISD5008SI chip utilizes a combination of analog and digital signal processing techniques. When recording, the chip converts the analog audio input into a digital format using an analog-to-digital converter (ADC). The digital audio data is then compressed and stored in non-volatile memory. During playback, the stored audio data is retrieved, decompressed, and converted back to analog using a digital-to-analog converter (DAC). The resulting analog signal is amplified and sent to the speaker output.
