The ISD4002-120EDR is an IC that is designed for voice recording and playback applications. It is based on 3rd generation CMOS technology and is designed to provide a low power, high performance and cost effective solution for interactive audio interfaces. This device provides a high-quality, low-noise audio recording and playback, while consuming minimal power.

The ISD4002-120EDR is a fully integrated, single-chip solution that is capable of recording up to 120 seconds of audio with low power consumption. It supports up to 8 kHz sampling rates and 8-bit resolution for recording, as well as playback. It features a low record current consumption of just 80 µA, and its playback current consumption is less than 800 µA. The ISD4002-120EDR also has a low power shutdown mode that provides a current consumption of less than 2 µA.

The ISD4002-120EDR is also designed with an on-chip RAM memory, which provides a low distortion and noise-free playback. It also has a high-speed mini-DIP Serial Flash Memory interface, providing an easy way to record and playback audio in a very short period of time. The ISD4002-120EDR also provides 64-bit random access memory for storing recorded audio and playback. Furthermore, it features a single-ended, active low trigger for playback, allowing for easy integration into audio systems.

The ISD4002-120EDR performs the recording and playback of audio with two independent channels, allowing for two-way audio communication. It also supports up to 8 kHz sample rate and 8-bit resolution per channel. The ISD4002-120EDR also provides triggered reset and power-down or power-save modes that reduce power consumption while the device is idle.

The working principle of the ISD4002-120EDR is based on sampling and digital signal processing. To record audio, the device uses an analog-to-digital converter (ADC) to convert analog signals into digital signals, which are then stored in the on-chip RAM. To playback audio, the device uses a digital-to-analog converter (DAC) to convert the digital signals back into analog signals, which can then be amplified and heard. The ISD4002-120EDR also features a low-power shutdown mode, which ensures that the device consumes minimal power when not in use.

The ISD4002-120EDR is an ideal solution for audio recording and playback applications, providing a high-performance, low-power and cost-effective interface. Its low-power shutdown mode ensures that it consumes minimal power when not in use and its on-chip RAM memory provides a low distortion and noise-free playback. Additionally, its high-speed mini-DIP Serial Flash Memory interface provides an easy way to record and playback audio in a very short period of time.
