Линейные изоляторы

Linear isolators 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.
