Working Principles

The ISD4003-05MPY utilizes ADPCM technology to compress and store audio data efficiently. During recording, the analog audio input is sampled and converted into a digital signal using a 4-bit ADPCM algorithm. The compressed audio data is then stored in the internal non-volatile memory. During playback, the stored data is retrieved, decompressed, and converted back into an analog audio signal for output.
