How it works

3 stages · Explore one step at a time

Step 1 / 3

Compare the inputs

The bipolar input stage responds to the difference between pins 3 and 2.

Step 2 / 3

Close the feedback loop

90 kΩ from OUT 6 to IN− 2 and 10 kΩ from IN− 2 to 0 V give a noise gain of ten.

Step 3 / 3

Budget real errors

Check offset, input currents, resistor tolerance, temperature and settling before reading a small signal.
