Working Principle of ISD4002-180PY

ISD4002-180PY works based on two main components: the analog-to-digital converter (ADC) and the digital-to-analog converter (DAC). The ADC converts the analog audio signal input into a digital signal, while the DAC converts the digital signal into an analog signal that can be played back.

For recording, the ADC converts the analog input signal into a digital format, so that it can be stored in the chip’s memory. For playback, the DAC converts the digital signal stored in the memory into an analog signal that can be outputted through a loudspeaker or audio jack.

The operating voltage for ISD4002-180PY is 5V or 3V DC, and it has a total of 16 pins, which can be used for various functions. These include power supply (4 pins), microphone (2 pins), common ground (2 pins), audio output (2 pins), recording/playback control (2 pins), voice activation (2 pins) and NAND Flash (4 pins).

ISD4002-180PY also features a built-in power monitoring function that can detect the power level and extend the recording/playback time under low power conditions. It also features high-quality ADPCM encoding, which allows for low-power performance and extended playback time.

Conclusion

In summary, ISD4002-180PY are highly integrated voice record and playback chips designed for use in a wide range of interface – voice applications. The component integrates a codec, power monitoring function, and high-quality ADPCM encoding, allowing for low-power performance and extended playback time. Additionally, the component can be used in low-cost intercoms, toys, distribution systems and home security systems.
