ADUM7640CRQZ Description

Short technical summary and product information.

The ADUM7640CRQZ is a 6-channel digital isolator based on Analog Devices' iCoupler technology. It provides 1000Vrms isolation, making it suitable for applications requiring functional isolation. Packaged in a small 20-lead QSOP, it offers space savings compared to higher isolation solutions.

 

This isolator operates with low power consumption and supports bidirectional communication with data rates up to 25Mbps. It features high common-mode transient immunity of over 15 kV/µs and a maximum pulse width distortion of 6ns. The device is designed for high-temperature operation up to 105°C.

 

Applications include general-purpose multichannel isolation, SPI interface isolation, and isolation for RS-232/RS-422/RS-485 transceivers. The ADUM7640CRQZ is surface mountable and designed for robust performance in industrial environments.
