Working Principles

ISD4002-120EYIR utilizes flash memory technology to store audio data. When in recording mode, the integrated circuit converts analog audio signals from the microphone input into digital format using the built-in ADC. The digital audio data is then stored in the non-volatile memory. During playback, the digital audio data is retrieved from memory and converted back into analog format using the DAC. The resulting analog signal is amplified and sent to the speaker output.
