GENERAL DESCRIPTION

The ADuM1300/ADuM1301

are triple-channel digital isolators

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

optocouplers.

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 of the power of

optocouplers at comparable signal data rates.

The ADuM1300/ADuM1301 isolators provide three independent

isolation channels in a variety of channel configurations and

data rates (see the Ordering Guide). Both 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 ADuM1300/ADuM1301 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 ADuM1300/ADuM1301 isolators

have a patented refresh feature that ensures dc correctness in the

absence of input logic transitions and when power is not applied

to one of the supplies.

Data Sheet ADuM1300/ADuM1301 APPLICATIONS INFORMATION DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY The ADuM1300/ADuM1301 digital isolator requires no external interface circuitry for the logic interfaces. Power supply bypassing is strongly recommended at the input and output supply pins (see Figure 14). Bypass capacitors are most conveniently connected between Pin 1 and Pin 2 for VDD1 and between Pin 15 and Pin 16 for VDD2. The capacitor value should be between 0.01 μF and 0.1 μF.
PAGE 26
ADuM1300/ADuM1301 Data Sheet 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 27
Data Sheet ADuM1300/ADuM1301 Note that the voltage presented in Figure 19 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 ADuM1300/ADuM1301 depends on the voltage waveform type imposed across the isolation barrier.
