Dual-Channel, Digital Isolators,

Enhanced System-Level ESD Reliability

ADuM3200/ADuM3201

GENERAL DESCRIPTION

FEATURES

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

Narrow body, 8-lead SOIC, Pb-free package

Low power operation

The ADuM320x¹are dual-channel, digital isolators based on

Analog Devices’ 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

1.6 mA per channel maximum @ 0 Mbps to 2 Mbps

3.7 mA per channel maximum @ 10 Mbps

7.5 mA per channel maximum @ 25 Mbps

3 V operation

1.4 mA per channel maximum @ 0 Mbps to 2 Mbps

2.4 mA per channel maximum @ 10 Mbps

4.6 mA per channel maximum @ 25 Mbps

Bidirectional communication

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 discrete

components is eliminated with these iCoupler products.

Furthermore, iCoupler devices consume one-tenth to one-sixth

the power of optocouplers at comparable signal data rates.

3 V/5 V level translation

High temperature operation: 105°C

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

The ADuM320x isolators provide two independent isolation

channels in a variety of channel configurations and data rates

(see the Ordering Guide). Both parts 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. The

ADuM320x isolators have a patented refresh feature that ensures

dc correctness in the absence of input logic transitions and

during power-up/power-down conditions.

DIN EN 60747-5-2 (VDE 0884 Part 2): 2003-01

DIN EN 60950 (VDE 0805): 2001-12; DIN EN 60950: 2000

V_IORM= 560 V peak

In comparison to the ADuM120x isolators, the ADuM320x

isolators contain various circuit and layout changes to provide

increased capability relative to system-level IEC 61000-4-x

testing (ESD, burst, surge). The precise capability in these tests

for either the ADuM120x or ADuM320x products is strongly

determined by the design and layout of the user’s board or

module. For more information, see Application Note AN-793,

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
