GENERAL DESCRIPTION

The ADuM1100 is a digital isolator based on Analog Devices’

iCoupler technology. Combining high speed CMOS and mono-

lithic air core transformer technology, this isolation component

provides outstanding performance characteristics superior to

alternatives such as optocoupler devices.

Configured as a pin compatible replacement for existing high speed

optocouplers, the ADuM1100 supports data rates as high as

25 Mbps and 100 Mbps.

The ADuM1100 operates with either voltage supply ranging from

3.0 V to 5.5 V, boasts a propagation delay of <18 ns and edge

asymmetry of <2 ns, and is compatible with temperatures up to

125°C. It operates at very low power, less than 0.9 mA of quiescent

current (sum of both sides), and a dynamic current of less than

160 µA per Mbps of data rate. Unlike other optocoupler alter-

natives, the ADuM1100 provides dc correctness with a patented

refresh feature that continuously updates the output signal.

The ADuM1100 is offered in three grades. The ADuM1100AR

and ADuM1100BR can operate up to a maximum temperature

of 105°C and support data rates up to 25 Mbps and 100 Mbps,

respectively. The ADuM1100UR can operate up to a maximum

temperature of 125°C and supports data rates up to 100 Mbps.
