Working Principles
ISD17240EYI01 utilizes a combination of analog and digital circuitry to enable audio recording and playback. When the REC pin is activated, the integrated circuit starts converting the incoming analog audio signal from the microphone input (MIC) into a digital format using the built-in ADC. The digital audio data is then stored in non-volatile memory.
During playback, the PLAY pin triggers the integrated circuit to retrieve the stored digital audio data from memory and convert it back into an analog signal using the built-in DAC. This analog signal is then amplified and sent to the speaker terminals (SPK+ and SPK-) for audio output.
Detailed Application Field Plans
ISD17240EYI01 finds applications in various electronic devices that require audio recording and playback capabilities. Some potential application fields include:
- Voice recorders
