Micro ampere meter circuit using uA 741


Posted on Feb 6, 2014

The micro ampere meter shown here is basically a DC millivolt meter. The circuit gives full scale deflection for 0. 1V input. The current to be measured is passed through a known resistance R and the voltage drop across it is measured. Here the IC 1 uA 741 op-amp is wired as a non inverting amplifier.
