Unlike optocoupler-based solutions, which have an uncertain current transfer ratio over a lifetime and is unstable at high temperatures, the ADuM4195-1 transfer function does not change over its lifetime, and is stable over a wide temperature range of −40°C to +125°C.
The ADuM4195-1 has been certified to provide galvanic isolation up to 5 kV rms according to UL1577.
The ADuM4195-1 is packaged in a small 8-lead wide body SOIC package with increased creepage.
