I am considering a circuit using AD8553.
QQ21: I want to switch the gain (900x, 200x, and 50x)
I would like to switch the resistor using an analog SW, but is there a better configuration?
Q2：I would like to build a filter with a cutoff frequency of 1KHz.
Datasheet Figure 2. What is the Gain vs. Frequency filter?
Is it the filter created with R2C2 in Figure 31?
I look forward to your reply
