ADUM2211TRIZ

产品概述

The ADUM2211 series dual-channel Digital Isolator based on Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology. It provides outstanding performance characteristics that are superior to alternatives such as optocoupler devices. By avoiding the use of LEDs and photodiodes, iCoupler device removes the design difficulties commonly associated with optocouplers. 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 run at one-tenth to one-sixth the power of optocouplers at comparable signal data rates. It provides two independent isolation channels in a variety of channel configurations and data rates.

• 5000Vrms High isolation voltage
• Low power operation
• High data rate of dc to 10Mbps (NRZ)
• 3ns Maximum pulse width distortion
• 3ns Maximum channel-to-channel matching
• >25kV/µs High common-mode transient immunity
