GENERAL DESCRIPTION

The ADuM220N/ADuM221N/ADuM225N/ADuM226N1 are

dual-channel digital isolators based on Analog Devices, Inc.,

iCoupler? technology. Combining high speed, complementary

metal-oxide semiconductor (CMOS) and monolithic air core

transformer technology, these isolation components provide

outstanding performance characteristics superior to alternatives

such as optocoupler devices and other integrated couplers. The

maximum propagation delay is 13 ns with a pulse width distortion

(PWD) of less than 3 ns at 5 V operation. Channel matching is

tight at 3.0 ns maximum.

The ADuM220N/ADuM221N/ADuM225N/ADuM226N data

channels are independent and are available in a variety of

configurations with a withstand voltage rating of 5.0 kV rms (see

the Ordering Guide). The devices operate with the supply voltage

on either side ranging from 1.8 V to 5 V, providing compatibility

with lower voltage systems as well as enabling voltage translation

functionality across the isolation barrier. Unlike other optocoupler

alternatives, dc correctness is ensured in the absence of input logic

transitions. Two different fail-safe options are available, in which

the outputs transition to a predetermined state when the input

power supply is not applied or the inputs are disabled. The

ADuM220N0 is pin compatible with the ADuM2210 RW-16

package. The ADuM220N1 is pin compatible with the

ADuM2200 RW-16 package. The ADuM221N0 is pin compatible

with the ADuM2211 RW-16 package. The ADuM221N1 is

pin compatible with the ADuM2201 RW-16 package.
