ADUM7440CRQZ Description

Short technical summary and product information.

The ADuM7440CRQZ from Analog Devices is a quad-channel digital isolator based on iCoupler® technology. It provides 1000 V rms isolation rating and is suitable for general-purpose multichannel isolation applications.

 

This device supports bidirectional communication with data rates up to 25 Mbps (NRZ). It operates with supply voltages ranging from 3 V to 5.5 V, enabling compatibility with lower voltage systems. The isolator features high common-mode transient immunity of greater than 15 kV/µs and low power consumption.

 

Packaged in a compact 16-lead QSOP, the ADUM7440CRQZ offers significant board space savings compared to traditional isolators. It is designed for high-temperature operation up to 105°C and includes an input glitch filter to protect against noise disturbances.

 

Key applications include SPI interface isolation, data converter isolation, and RS-232/RS-422/RS-485 transceivers. The device meets safety and regulatory approvals such as UL 1577.
