Other Parts Discussed in Thread: OPA333
Tool/software:
Currently designing a radar level gauge product
The INA827 circuit was used, as shown in the following figure.
Now debugging has found that its differential frequency signal output value is relatively small,
How to set the parameters of the two-stage RC circuit after the IF signal range of 3K-40K.
How to set the gain to achieve the optimal SNR value.
Thank you for your attention. Thank you
