GENERAL DESCRIPTION
The ADuM240x are four-channel digital isolators based on
Analog Devices’ iCoupler® technology. Combining high speed
CMOS and monolithic air core transformer technology, these
isolation components provide outstanding performance
characteristics superior to alternatives such as optocoupler
devices. In comparison to the 2.5KV ADuM140x product
family, ADuM240x models have increased insulation thickness
to achieve the higher 5.0KV isolation rating.
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with
optocouplers. The typical optocoupler concerns regarding
uncertain current transfer ratios, nonlinear transfer functions,
and temperature and lifetime effects are eliminated with the
simple, iCoupler digital interfaces and stable performance
characteristics. The need for external drivers and other discretes
is eliminated with these iCoupler products. Furthermore,
iCoupler devices run at one-tenth to one-sixth the power
consumption of optocouplers at comparable signal data rates.
The ADuM240x isolators provide four independent isolation
channels in a variety of channel configurations and data rates (see
Ordering Guide). All ADuM240x models operate with the supply
voltage of either side ranging from 2.7 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier. In
addition, the ADuM240x provides low pulse width distortion (<2
ns for CRWZ grade), and tight channel-to-channel matching (<2
ns for CRWZ grade). Unlike other optocoupler alternatives, the
ADuM240x isolators have a patented refresh feature that ensures
dc correctness in the absence of input logic transitions and during
power-up/power-down conditions.

NOTES
1 All voltages are relative to their respective ground.
2 Supply current values are for all four channels combined running at identical data rates. Output supply current values are specified with no output load present. The
supply current associated with an individual channel operating at a given data rate may be calculated as described in the Power Consumption section on page 20.
See Figure 8 through Figure 10 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 11 through
Figure 14 for total IDD1 and IDD2 supply currents as a function of data rate for ADuM2400/ADuM2401/ADuM2402 channel configurations.
3 The minimum pulsewidth is the shortest pulsewidth at which the specified pulsewidth distortion is guaranteed.
4 The maximum data rate is the fastest data rate at which the specified pulsewidth distortion is guaranteed.
5 tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay
is measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal.
6 tPSK is the magnitude of the worst-case difference in tPHL or tPLH that will be measured between units at the same operating temperature, supply voltages, and output
load within the recommended operating conditions.
7 Co-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of
the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels
with inputs on opposing sides of the isolation barrier.
8 CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8VDD2. CML is the maximum common-mode voltage slew rate
than can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The
transient magnitude is the range over which the common mode is slewed.
9 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 8 through Figure 10 for
information on per-channel supply current for unloaded and loaded conditions. See Power Consumption section on page 19 for guidance on calculating per-
channel supply current for a given data rate.
