FAQ

What is the typical input bias current for the AD71057?

The AD71057 features a JFET input stage, resulting in a very low input bias current, typically in the picoampere range.

Does the AD71057 support rail-to-rail output?

No, the AD71057 uses a CMOS output stage but does not achieve true rail-to-rail output swing; it typically swings within a few hundred millivolts of the supply rails.
