OPA211: The bias current questions
TI Thinks Resolved
Part Number:
OPA211
Hi, I am a hardware engineer. I have some questions about the op amp bias current. Q1: The bias current is supplied by the external circuit or the internal circuit? Q2: If the bias current is supplied by the external circuit...

RE: OPA211: OPA211 powered single-supply 3.3V?
Hi Andreas, The datasheet recommended to have minimum voltage of 4.5V as operating conditions in a single voltage supply. Even if the part works at 3.3V, it may not get the linear responses the op amp output. Using 4.5V as the single rail power supply...
