Working Principles

ISD4003-04MSIR utilizes flash memory technology to store audio data. When in record mode, the microphone input converts analog audio signals into digital format using the built-in ADC. The digital audio data is then stored in the flash memory. During playback, the stored data is retrieved from the flash memory and converted back to analog format using the DAC. The analog audio signal is then amplified and sent to the speaker output.
