ADUM1301ARWZ General Purpose Digital Isolator 2500Vrms 3 Channel 1Mbps 25kV/µs CMTI

GENERAL DESCRIPTION

The ADuM130x are 3-channel digital isolators based on Analog

Devices’ iCoupler® technology. Combining high speed CMOS

and monolithic transformer technology, these isolation compo-

nents provide 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 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 discretes

is eliminated with these iCoupler products. Furthermore,

iCoupler devices consume one-tenth to one-sixth the power of

optocouplers at comparable signal data rates.

The ADuM130x isolators provide three independent isolation

channels in a variety of channel configurations and data rates

(see the Ordering Guide). Both models 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 ADuM130x provides low pulse-width distortion

(<2 ns for CRW grade) and tight channel-to-channel matching

(<2 ns for CRW grade). Unlike other optocoupler alternatives,

the ADuM130x isolators have a patented refresh feature that

ensures dc correctness in the absence of input logic transitions

and during power-up/power-down conditions.

Product Attributes

Koben Electronics was founded in 1995 and is located in the Silicon Valley of China, Shenzhen.

The mission of Koben has always been to provide quality electronics components to manufacturers worldwide. Early on we became a primary conduit for end-of-program and overstock inventory for major distributors such as Future Electronics and contract manufacturers as Flextronics. Koben has since then added sourcing of high quality components from local manufacturers in China.

Koben has always been customer driven rather than opportunity driven. Meaning- we will always choose path that is best for long term relationship with customer over short term view. It is why we have one of the highest customer retention scores of China based distributors.
