Analog Devices / Maxim Integrated MAX22517 Dual-Channel Digital Galvanic Isolators

Analog Devices MAX22517 Dual-Channel Digital Galvanic Isolators have an integrated field-side supply using proprietary process technology. The field-side power is supplied by the logic-side using an integrated isolated DC-DC converter. This approach eliminates the bulky and expensive external isolated power supply when the power demand of the field side is small. Analog Devices MAX22517 Dual-Channel Digital Galvanic Isolators operate in a -40°C to +125°C temperature range.
