Working Principles

ISD4003-04MSI utilizes a combination of analog and digital circuitry to enable audio recording and playback. When the REC pin is activated, the integrated ADC converts the incoming analog audio signal from the microphone into a digital format, which is then stored in non-volatile memory. During playback, the stored digital audio data is retrieved from memory and converted back into an analog signal by the integrated DAC. This analog signal is then amplified and sent to the speaker for audio output.
