ADuM4195-1 Description
The ADuM4195-11 is an isolation amplifier based on Analog Devices, Inc., iCoupler® technology. The ADuM4195-1 has very low offset and gain error, making it ideal for many isolated voltage sensing applications. 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...
