Analog Devices Inc. ADUM7642ARQZ-RL7

The ADUM7642ARQZ-RL7 is a 1 kV RMS six-channel digital isolator produced by Analog Devices Inc. This component is part of the ADuM7640/ADuM7641/ADuM7642/ADuM7643 family, which utilizes Analog Devices' iCoupler® technology. It is packaged in a compact 20-lead QSOP, offering significant space savings and a lower cost compared to higher isolation voltage solutions when only functional isolation is required. The device is designed for low power consumption, operating with supply voltages ranging from 3.0 V to 5.5 V on either side, making it suitable for a variety of applications where energy efficiency is crucial.

• Low Power Consumption: The ADUM7642ARQZ-RL7 uses one-tenth to one-sixth the power of other digital isolators, making it highly energy-efficient.
• High Data Rate: Supports data rates up to 25 Mbps, ensuring high-speed communication.
• High Common-Mode Transient Immunity: Offers >15 kV/µs common-mode transient immunity, providing robust protection against noise disturbances.
• Channel-by-Channel Glitch Filter: Protects the device against extraneous noise disturbances with a built-in glitch filter.
• Default Output High Logic State: Ensures that the output defaults to a high logic state in the absence of input power.
• 3 V/5 V Level Translation: Supports level translation between 3 V and 5 V systems, enhancing versatility in various applications).

• General-Purpose, Multichannel Isolation: Suitable for isolating multiple channels in various industrial and commercial applications).
• SPI Interface/Data Converter Isolation: Ideal for isolating SPI interfaces and data converters to ensure reliable and noise-free communication).
• RS-232/RS-422/RS-485 Transceivers: Used in serial communication systems to provide isolation and protect against voltage spikes and noise).
• Industrial Field Bus Isolation: Applicable in industrial field bus systems to ensure reliable and isolated communication between different segments of the network).
