Hello,
I am using a UAF 42 ic for 60 hz low pass notch filter. i have taken the circuit from the application notes document..
i have attached the circuit. the problem with the circuit is that when i give a input of any frequency from 10 to 100hz. with amplitude 7v, i got a constant output volt of 12 v. I didn,t used the pin V-. as i shown in fig
Please suggest us.
