Hi everyone,
please i am having an issue, with my circuit, i built an non inverting amplifier with a a gain of around 100, the input to the op amp is form a shunt whose output is 100mv@10A ,everything works fine when the input voltage is above 50mV, but when my input is about 40mV output gain begins to be unstable, and lower input the lower the output gain.
it got to a point were i had 2.0mV and my output was 10.1mV. And i intend measuring from 0.1mv(10mA) to 200mv(2A). please i would really appreciate if anyone could help me one this...i have been on this for quite some days now
