Isolation Amplifiers
Isolation Amplifiers provide power supply designers with a higher performing, single chip alternative to isolation techniques based on optocouplers and shunt regulators. Analog Devices ADuM3190 and ADuM4190 isolated error amplifiers have a 400 kHz bandwidth, with 0.5% typical initial accuracy at 25°C and 1% total accuracy over the extended temperature range of –40˚C to +125˚C. This provides manufacturers of ac-to-dc and dc-to-dc power supplies with a significant upgrade in speed and operating temperature range, as well as a 5× improvement in transient response.
Product Selection Table
Safety and Regulatory Compliance Information
The iCoupler family of digital isolation products have been tested and approved by various regulatory agencies, including UL, CSA, VDE, TÜV, CQC, ATEX and IECEx. This table summarizes the achieved ratings for each product and includes links to copies of the actual safety certificates.
EMC Resources
Whether as a component or as part of a larger system level solution, EMC compliance must be met, and the best EMC design practices occur at the start of the design. Be prepared for the certification process and get ahead of the game with our selection of resources.
