ANALOG DEVICES - ADUM1100ARZ - HIGH SPEED DIGITAL ISOLATOR, SMD

The ADUM1100ARADUM1100AR is a digital isolator based on Analog Devices Inc. iCoupler® technology. Combining high speed CMOS and monolithic 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 ADUM1100ARADUM1100AR supports data rates as high as 25 Mbps and 100 Mbps.

The ADUM1100ARADUM1100AR operates with a 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 alternatives, the ADUM1100ARADUM1100AR provides dc correctness with a patented refresh feature that continuously updates the output signal.

The ADUM1100ARADUM1100AR is offered in three grades. The ADUM1100ARADUM1100AR 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.
