GENERAL DESCRIPTION

The ADuM1200/ADuM1201

are dual-channel digital isolators

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

Combining high speed CMOS and monolithic transformer

technologies, these isolation components provide outstanding

performance characteristics superior to alternatives, such as

optocouplers.

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 temper-

ature 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.

The ADuM1200/ADuM1201 isolators provide two independent

isolation channels in a variety of channel configurations and

data rates (see the Ordering Guide). Both devices 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 ADuM1200/ADuM1201 provide low

pulse width distortion (<3 ns for CR grade) and tight channel-

to-channel matching (<3 ns for CR grade). Unlike other

optocoupler alternatives, the ADuM1200/ADuM1201 isolators

have a patented refresh feature that ensures dc correctness in

the absence of input logic transitions and during power-

up/power-down conditions.

The ADuM1200W and ADuM1201W are automotive grade

versions qualified for 125°C operation. See the Automotive

Products section for more information.

ADuM1200/ADuM1201 Data Sheet APPLICATIONS INFORMATION The capacitor value should be between 0.01 μF and 0.1 μF. The total lead length between both ends of the capacitor and the input power supply pin should not exceed 20 mm. See the AN-1109 Application Note for board layout guidelines. PROPAGATION DELAY-RELATED PARAMETERS Propagation delay is a parameter that describes the time it takes a logic signal to propagate through a component.
PAGE 25
Data Sheet ADuM1200/ADuM1201 For example, at a magnetic field frequency of 1 MHz, the maximum allowable magnetic field of 0.2 kgauss induces a voltage of 0.25 V at the receiving coil. This is about 50% of the sensing threshold and does not cause a faulty output transition. Similarly, if such an event occurs during a transmitted pulse (and has the worst-case polarity), it reduces the received pulse from >1.0 V to 0.75 V—still well above the 0.5 V sensing threshold of the decoder.
PAGE 26
ADuM1200/ADuM1201 Data Sheet Note that the voltage presented in Figure 16 is shown as sinusoidal for illustration purposes only. It is meant to represent any voltage waveform varying between 0 V and some limiting value. The limiting value can be positive or negative, but the voltage cannot cross 0 V. The insulation lifetime of the ADuM1200/ADuM1201 depends on the voltage waveform type imposed across the isolation barrier.
