Quad-Channel Digital Isolators
ADuM1400/ADuM1401/ADuM1402
FEATURES
GENERAL DESCRIPTION
Qualified for automotive applications
The ADuM1400/ADuM1401/ADuM14021 are quad-channel
Low power operation
digital isolators based on Analog Devices, Inc., iCoupler®
5 V operation
technology. Combining high speed CMOS and monolithic air
1.0 mA per channel maximum at 0 Mbps to 2 Mbps
core transformer technology, these isolation components provide
3.5 mA per channel maximum at 10 Mbps
outstanding performance characteristics superior to alternatives,
31 mA per channel maximum at 90 Mbps
such as optocoupler devices.
3 V operation
0.7 mA per channel maximum at 0 Mbps to 2 Mbps
2.1 mA per channel maximum at 10 Mbps
20 mA per channel maximum at 90 Mbps
Bidirectional communication
3 V/5 V level translation
High temperature operation: 125°C
High data rate: dc to 90 Mbps (NRZ)
Precise timing characteristics
2 ns maximum pulse width distortion
2 ns maximum channel-to-channel matching
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with opto-
couplers. 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 discrete components is
eliminated with these iCoupler products. Furthermore, iCoupler
devices consume one tenth to one sixth of the power of
optocouplers at comparable signal data rates.
High common-mode transient immunity: >25 kV/μs
Output enable function
16-lead SOIC wide body package

CSA Component Acceptance Notice 5A
VDE Certificate of Conformity
DIN V VDE V 0884-10 (VDE V 0884-10):2006-12
VIORM = 560 V peak
TÜV approval: IEC/EN/UL/CSA 61010-1
The ADuM1400/ADuM1401/ADuM1402 isolators provide four
independent isolation channels in a variety of channel configu-
rations and data rates (see the Ordering Guide). All models
operate with the supply voltage on 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 ADuM1400/
ADuM1401/ADuM1402 provide low pulse width distortion
(<2 ns for CRW grade) and tight channel-to-channel matching
(<2 ns for CRW grade). Unlike other optocoupler alternatives, the
ADuM1400/ADuM1401/ADuM1402 isolators have a patented
APPLICATIONS

SPI interface/data converter isolation
refresh feature that ensures dc correctness in the absence of input
logic transitions and when power is not applied to one of the
supplies.

1 All voltages are relative to their respective ground.
2 The supply current values for all four channels are combined when 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.
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 15 for total VDD1 and VDD2 supply currents as a function of data rate for ADuM1400/ADuM1401/ADuM1402 channel configurations.
3 The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed.
4 The maximum data rate is the fastest data rate at which the specified pulse width 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 is measured between units at the same operating temperature, supply voltages, and output load
within the recommended operating conditions.
7 Codirectional 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 > 0.8 VDD2. CML is the maximum common-mode voltage slew rate
that 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 the Power Consumption section for guidance on calculating the per-channel supply current
for a given data rate.
