Step 1 / 3

Compare each input pair

The CMOS inputs have very low typical bias current at room temperature. Leakage increases with temperature, and board contamination or high source impedance can dominate the error.

Step 2 / 3

Set two different gains

Channel A uses 20 kΩ feedback and 10 kΩ to the 0 V midpoint, giving a gain of three. Channel B directly feeds its output back to its negative input, giving unity gain.

Step 3 / 3

Check headroom and speed

With a 0.50 V input, the ideal outputs are 1.50 V and 0.50 V. Real output also depends on input offset, resistor accuracy, loading, noise and signal frequency.
