GENERAL DESCRIPTION

The ADuM15101 is a unidirectional, 5-channel isolator based

on the Analog Devices, Inc., iCoupler® technology. Combining

high speed CMOS and monolithic air core transformer technology,

these isolation components provide outstanding performance

characteristics superior to alternatives such as optocoupler devices.

By avoiding the use of LEDs and photodiodes, iCoupler devices

eliminate the design difficulties commonly associated with

optocouplers. The 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 iCoupler products. In addition,

iCoupler devices run at one-tenth to one-sixth the power

consumption of optocouplers at comparable signal data rates.

The ADuM1510 isolator provides five independent isolation

channels supporting data rates up to 10 Mbps. The ADuM1510

operates with the supply voltage of either side ranging from 4.5 V

to 5.5 V. Unlike other optocoupler alternatives, the ADuM1510

isolator has a patented refresh feature that ensures dc correctness in

the absence of input logic transitions and during power-up/

power-down conditions.
