GENERAL DESCRIPTION
The ADuM640x1 devices are quad-channel digital isolators with
isoPower®, an integrated, isolated dc-to-dc converter. Based on
the Analog Devices, Inc., iCoupler® technology, the dc-to-dc

converter provides up to 500 mW of regulated, isolated power at
either 5.0 V or 3.3 V from a 5.0 V input supply, or 3.3 V from a
3.3 V supply at the power levels shown in Table 1. This eliminates
the need for a separate, isolated dc-to-dc converter in low power,
isolated designs. The iCoupler chip scale transformer technology
is used to isolate the logic signals and for the magnetic components

of the dc-to-dc converter. The result is a small form factor, total
isolation solution.
The ADuM640x isolators provide four independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide for more information).

isoPower uses high frequency switching elements to transfer
power through its transformer. Special care must be taken
during printed circuit board (PCB) layout to meet emissions
standards. Refer to the AN-0971 application note for board
layout recommendations at www.analog.com.

1 |CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 × VDD1 or 0.8 × VISO for a high input or VO < 0.8 × VDD1 or 0.8 × VISO for
a low input. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges.
ELECTRICAL CHARACTERISTICS—5 V PRIMARY INPUT SUPPLY/3.3 V SECONDARY ISOLATED SUPPLY
All typical specifications are at TA = 25°C, VDD1 = 5.0 V, VISO = 3.3 V, VSEL = GNDISO. Minimum/maximum specifications apply over the
entire recommended operation range which is 4.5 V ≤ VDD1 ≤ 5.5 V, 3.0 V ≤ VISO ≤ 3.6 V; and −40°C ≤ TA ≤ +105°C, unless otherwise
noted. Switching specifications are tested with CL = 15 pF and CMOS signal levels, unless otherwise noted.
