Working Principles

ISD17120EY01 utilizes analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC) techniques to record and play back audio. When in record mode, the microphone input is sampled and converted into a digital format, which is then stored in non-volatile memory. During playback, the stored digital audio data is retrieved from memory and converted back into an analog signal for output.
