Working Principles

ISD4002-150P utilizes flash memory technology to store and retrieve audio data. It employs a combination of analog and digital signal processing techniques to ensure high-quality audio reproduction.

During recording, the analog audio input is converted into a digital format using an internal ADC (Analog-to-Digital Converter). The digital audio data is then stored in the flash memory.

During playback, the stored digital audio data is retrieved from the flash memory and converted back into an analog signal using a DAC (Digital-to-Analog Converter). The analog audio output can be further amplified for driving speakers or other audio devices.
