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.
