Other Parts Discussed in Thread: TINA-TI, TL052
Hi team,
I have some questions about the transimpedance amplifiers.
How to calculate the CF value? Which formula can I use?
E.g. OPA847, I note the formula 1 of the datasheet which is on page 11 and
the formula 5 of the datasheet which is on page 12.
Q1 So, Based on the stability of the op amp, I want to verify if the formula 1 of the OPA847 datasheet
is derived by the Figure 2 BodePlot Magnitude of the above document.
If this is true, I can use the formula 1 of the OPA847 datasheet to calculate the CF value,correct?
Q2. What is the formula 5 of the OPA847 datasheet which is on page 12? When can I use this
formula to calculate the CF value? Could you explain the formula 5? How to determine
the Zo value and NG2 value to calculate the CF value?
Q3. For the formula 1 and formula 5, could you give me an example for each formula ?
