I am using this current-sense amplifier. When i change the load resistance, the output of amplifier increases and decreases in the form of ramp. I want it to change in the form of square wave. I am using Lm139 opamp.
In what function do you use it? Do you mean the two OPs drawn in the rectangle? LM139 is an open collector comparator (uncompensated, unstable as amplifier), not an OP.I am using Lm139 opamp
