ADUM1210 Dual-Channel Digital Isolator

Applications Size-critical multichannel isolation SPI interface/data converter isolation RS-232/RS-422/RS-485 transceiver isolation Digital field bus isolation Gate drive interface

The ADuM1210 is a dual-channel, digital isolator based on Analog Devices, Inc. iCoupler® technology. Combining high speed CMOS and monolithic transformer technology, this isolation component provides outstanding performance characteristics superior to alternatives such as optocoupler devices.

By avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers. The concerns of the typical optocoupler 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 iCoupler products. Furthermore, iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates.

The ADuM1210 isolator provides two independent isolation channels operable with the supply voltage on either side, ranging from 2.7 V to 5.5 V. This provides compatibility with lower voltage systems and enables voltage translation functionality across the isolation barrier. In addition, the ADuM1210 provides low pulse width distortion (<3 ns) and tight channel-to-channel matching (<3 ns). Unlike other optocoupler alternatives, the ADuM1210 isolator has a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions. Furthermore, as an alternative to the ADuM1200 dual-channel digital isolator that defaults to an output high condition, the ADuM1210 outputs default to a logic low state when input power is off.
