GENERAL DESCRIPTION
The ADuM7640/ADuM7641/ADuM7642/ADuM7643
1
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.
