Working Principles

ISD4004-10MEI utilizes flash memory technology to store audio data. When recording, the analog audio signal is converted into a digital format using the built-in ADC. 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 the built-in DAC. This analog signal can then be amplified and output through a speaker or other audio output device.

Detailed Application Field Plans

ISD4004-10MEI finds applications in various fields, including but not limited to:

1. Voice recorders
2. Message playback systems
3. Alarm systems
4. Toys with audio features
5. Automotive audio systems
6. Medical devices with audio recording capabilities
