Working Principles

ISD4002-150SY utilizes non-volatile memory technology to store audio data. The device converts analog audio signals into digital format using an integrated ADC (Analog-to-Digital Converter). The digital audio data is then compressed and stored in the non-volatile memory. During playback, the stored data is retrieved, decompressed, and converted back into analog audio signals using a DAC (Digital-to-Analog Converter). The resulting audio output can be amplified and played through an external speaker or headphone.

Detailed Application Field Plans

ISD4002-150SY finds applications in various fields, including: 1. Voice recorders 2. Message playback systems 3. Alarm systems with voice prompts 4. Interactive toys and games 5. Automotive audio systems 6. Medical devices with audio feedback
