ISD4004-08MEIR application field and working principle

Voice record and playback technology has become an integral part of modern communication. One of the most popular systems for this purpose is the ISD4004-08MEIR—a multi-layer, multi-function interface that can be integrated into a wide range of applications. This article will explore the application fields of this system, as well as its workings and benefits.

Characteristics and Working Principle

The ISD4004-08MEIR is a high-performance, low-power single-chip integrated circuit that features 8-millisecond sampling time and 24-minutes recording capability. It has an integrated pre-amplifier, power supply DC-DC converter, interface ADC/DAC and signal processor as well as an integrated Record Playback/Auto Playback circuit.

The chip integrates an 8-channel selectable pre-amplifier, which has a high voltage gain, low noise and low power consumption. This pre-amplifier is used to amplify incoming signals before reaching the signal processor or ADC/DAC converter. The signal processor then analyzes the signal, filters out unwanted frequencies and prepares the signal for recording or playback. The ADC/DAC converter is responsible for converting the analog signal into a digital format for recording or playback.

When recording, the ISD4004-08MEIR converts an analog signal into a digital format, stores it in a non-volatile memory and compresses it. When playing back the signal, the system reverse the process and delivers the comments via a headphone or speaker.

Application Fields

The ISD4004-08MEIR is applicable to a wide range of recording and playback applications, such as home audio systems, conference systems, speech recognition systems, dictation systems, computer networks and more. The system also allows for single and multiple channel recording and playback.
