Quick Detail:
Dual-Channel Digital Isolators
Description:
The ADuM120x are dual-channel digital isolators based on Analog Devices’ iCoupler® technology. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alter natives such as opto coupler devices.
By avoiding the use of LEDs and photo diodes, iCoupler devices
remove the design difficulties commonly associated with
opto couplers. The typical opto coupler concerns regarding
uncertain current transfer ratios, nonlinear transfer functions,
and temperature and lifetime effects are eliminatedwith the
simple iCoupler digital interfaces and stable performance
characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products.
Further more, iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates.
The ADuM120x isolators provide two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). Both parts 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 ADuM120x provide low pulse-width distortion (< 3 ns for CR grade) and tight channel-to-channel matching (< 3 ns for CR grade). Unlike other optocoupler alternatives, the ADuM120x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions.
