Introduction

The ISD5008ZD is an integrated circuit used in interface – voice record and playback applications. It is an 8-channel monolithic analog/digital audio data acquisition, record and playback device. With CE compliant, it is widely used in consumer applications such as dictation machines and digital voicemail systems.The ISD5008ZD integrates a low power Microcontroller, Memory and an analog-to-digital converter in a very small footprint providing an easy to implement solution for voice record and playback applications.

Features and Functions

The main features of the ISD5008ZD are as follows:- Voice record/playback - Supports 8-Channel mono recording and playback.- Non-volatile memory - Includes 4Mbit of non-volatile memory for storage and playback.- Digital to analog conversion - On-chip Digital to Analog conversion with 16-bit resolution.- Low power consumption - Consumes only 15mA for record/playback mode.- Electrostatic Discharge Protection Technology (ESD) - Built-in Electrostatic Discharge Protection Technology (ESD) to protect against high voltage surges.

Application Fields and Working Principle

The ISD5008ZD is designed to be used in voice record and playback applications. It is a highly integrated design with an analog-to-digital converter, non-volatile memory, and a low power Microcontroller, designed to maximize system performance while minimizing power consumption. The integrated memory and digital-to-analog converter in the ISD5008ZD offer the utmost flexibility in design.The ISD5008ZD can be used to record and playback up to 8-channels of monophonic sound. It utilizes 16-bit AD conversion for sound data acquisition and Low Power consumption for playback and recording. The playback sound format is 8 bytes of mono PCM data. The data acquisition is highly accurate though the integrated analogue-to-digital converter.The ISD5008ZD also utilizes built-in Electrostatic Discharge Protection Technology (ESD) to protect against high voltage surges. The Low Power consumption of ISD5008ZD ensures that the device can be used in battery operated applications.Due to its small footprint and integrated 8-Channel mono recording and playback, the ISD5008ZD is ideal for applications such as digital voicemail systems, voice recorders, dictation machines, and more.

Conclusion

The ISD5008ZD is a highly integrated design with an analog-to-digital converter, non-volatile memory, and a low power microcontroller. It is an ideal solution for interface – voice record and playback applications such as digital voicemail systems, voice recorders, and dictation machines. The integrated memory and digital-to-analog converter offer flexible design options while the built-in Electrostatic Discharge Protection Technology (ESD) keeps external high voltage surges at bay. The low power consumption ensures that the device can be used in battery operated applications.
