Q
Can the ADuM3190/4190 isolated error amplifier be used as an isolation
amplifier?
A
The ADuM3190 and ADuM4190 are ideal for linear feedback in isolated power
supply applications. Since they have an amplifier input and isolated amplifier
output they can be used as an isolated amplifier in limited ways. The ADuM3190
and ADuM4190 have only a single supply voltage and do not have bipolar inputs,
just unipolar inputs from 0.35V to 1.5V. The outputs are single ended, not
differential. It is important to review the output voltages and the offset,
gain and other specifications to see how the ADuM3190/ADuM4190 will perform in
your application.
