Other Parts Discussed in Thread: LM7705, OPA333
The circuit schematic is shown below.Using OPA2333 as a voltage follower. The conversion error is large, why?
FLUKE(754) test circuit at 30 ° C. UA=1V. UB = 0.9983V. UC = 0.9997V.
IB of OPA2333 is 200pA,IOS of OPA2333 is 400pA. Why UA-UB=1.7mV? Why UC is greater than UB?
