Part Number: UCD3138A

Team,

How does the internal offset error of the error amplifier of UCD3138A depend on common voltage?

Are there any precautions necessary to keep this internal offset as low as possible?

Thanks for your help,

Hi,

Internal amplifier can handle common mode voltage, as far as I know, the offset is very small and doesn't cause any problem. But keep input impedance smaller, such as few kilo ohms.

Sean
