Dual-Channel, Digital Isolators,

Enhanced System-Level ESD Reliability

Data Sheet

ADuM3200/ADuM3201

FEATURES

GENERAL DESCRIPTION

Enhanced system-level ESD performance per IEC 61000-4-x

High temperature operation: 125°C

Narrow body, RoHS-compliant, 8-lead SOIC

Low power operation

The ADuM3200/ADuM3201¹are dual-channel, digital isola-

tors based on the Analog Devices, Inc., iCoupler® technology.

Combining high speed CMOS and monolithic transformer

technology, these isolation components provide outstanding

performance characteristics superior to alternatives such as

optocoupler devices.

5 V operation

1.7 mA per channel maximum @ 0 Mbps to 2 Mbps

3.7 mA per channel maximum @ 10 Mbps

7.0 mA per channel maximum @ 25 Mbps

3 V operation

1.5 mA per channel maximum @ 0 Mbps to 2 Mbps

2.5 mA per channel maximum @ 10 Mbps

4.7 mA per channel maximum @ 25 Mbps

Bidirectional communication

3 V/5 V level translation

High data rate: dc to 25 Mbps (NRZ)

Precise timing characteristics

3 ns maximum pulse width distortion

3 ns maximum channel-to-channel matching

High common-mode transient immunity: >25 kV/μs

Safety and regulatory approvals

UL recognition: 2500 V rms for 1 minute per UL 1577

CSA Component Acceptance Notice #5A

VDE Certificate of Conformity

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 char-

acteristics. The need for external drivers and other discrete

components is eliminated with these iCoupler products. Further-

more, iCoupler devices consume one-tenth to one-sixth the

power of optocouplers at comparable signal data rates.

The ADuM3200/ADuM3201 isolators provide two independent

isolation channels in a variety of channel configurations and

data rates (see the Ordering Guide). They operate with 3.3 V

or 5 V supply voltages on either side, providing compatibility

with lower voltage systems as well as enabling voltage translation

functionality across the isolation barrier. The ADuM3200W

and ADuM3201W are automotive grade versions qualified

for 125°C operation.

DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12

_IORM= 560 V peak

Qualified for automotive applications

In comparison to the ADuM120x isolators, the ADuM3200/

ADuM3201 isolators contain various circuit and layout changes

to provide increased capability relative to system-level IEC

61000-4-x testing (ESD, burst, and surge). The precise capability

in these tests for either the ADuM120x or ADuM3200/

ADuM3201 products is strongly determined by the design and

layout of the user’s board or module. For more information, see

the AN-793 Application Note, ESD/Latch-Up Considerations with

iCoupler Isolation Products.

APPLICATIONS

Size-critical multichannel isolation

SPI interface/data converter isolation

RS-232/RS-422/RS-485 transceiver isolation

Digital field bus isolation

Hybrid electric vehicles, battery monitor
