LM2901

Other Parts Discussed in Thread: LM2901

Dear sir, please answer

I used circuit (please see attach) at 50 mV at the “A” point . Max voltage at the LM2901 input is 60-70 mV. Circuit worked well. Circuit designed for determine the approximate value of the voltage across the resistor R1.

I need to use this circuit at 10 mV at the “A” point now. Max voltage at the LM2901 input is 15 mV.

How do you think, is it make sense to install 100…1000 pF capacitors between inputs of LM2901 and GND for reducing noise and prevent false switching?

TIA

Sincerely

Vladimir Naumenkov
