Description

General part information

ADUM7643 Series

TheADuM7640/ADuM7641/ADuM7642/ ADuM7643 are 6-channel digital isolators based on the Analog Devices, Inc.,iCoupler®technology. These 1 kV digital isolation devices are packaged in a small 20-lead QSOP. They offer space savings and a lower price than 2.5 kV or 5 kV isolation solutions when only functional isolation is needed.This family, like many Analog Devices isolators, offers very low power consumption, using one-tenth to one-sixth the power of other digital isolators, with the supply voltage on either side ranging from 3.0 V to 5.5 V. Despite their low power consumption, the ADuM7640 / ADuM7641 / ADuM7642 / ADuM7643 provide low pulse width distortion (< 6 ns for C grade) and a channel- by-channel glitch filter to protect the device against extraneous noise disturbances. Four channel direction combinations are available with a maximum data rate of 1 Mbps or 25 Mbps. All products have a default output high logic state in the absence of input power.ApplicationsGeneral-purpose, multichannel isolationSPI interface/data converter isolationRS-232/RS-422/RS-485 transceiversIndustrial field bus isolation
