ADUM5211

Dual-Channel Isolators with Integrated DC/DC Converter (1/1 Channel Directionality)
Manufactured by:

Product Details

The ADuM5210/ADuM5211/ADuM5212 are dual-channel digital isolators with isoPower®, an integrated, isolated DC/DC converter. Based on the Analog Devices, Inc., iCoupler® technology, the DC/DC converter provides regulated, isolated power, adjustable between 3.15 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher.

This eliminates the need for a separate, isolated DC/DC converter in low power, isolated designs. The iCoupler chip-scale transformer technology is used for isolated logic signals and for the magnetic components of the DC/DC converter. The result is a small form factor, total isolation solution.

isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for board layout recommendations.

Applications
  • RS-232 transceivers
  • Power supply start-up bias and gate drives
  • Isolated sensor interfaces
  • Industrial PLCs

ADUM5211 is a device that is easy to use. Low cost, miniaturization has been made. This product is pin are separated, the noise of the DC / DC is also easier to deal with. The supply organization of this device of yours is anxious. I expect that time for delivery will become short.

a basic performance is good, but i didn't test EMI/EMC yet. and price is some high. so i recommend ADI to reduce the price a little, to exceed the competitor.

TTL isolator with ISO-power rocks
The independent isolated power supply included in these isolators make it really easy for isolating incoming TTL signals without much hassle and no extra IC's.

ADUM5211 Isolator Provided an Easy UL Fix
We have a product that needed to get UL certification, and the one thing not compliant was a 1-wire iButton interface. Since the iButton signals went straight into the microcontroller with just some RLC components and ESD protection, it didn't pass the dielectric tests. The ground and signal were not isolated from the outside world. Adding a ADUM5211 isolator to the 1-wire interface provided a quick fix by giving it the needed high-voltage barrier. Another bonus is that the ADUM5211 takes less power than the previous generation ADUM5241, avoiding a thermal issue with a voltage regulator.
