power supply with a 0.1μF ceramic capacitor placed
close to the V
DD
pin. If operating from dual supplies,
bypass each supply to ground.
Good layout improves performance by decreasing the
amount of stray capacitance and noise at the op amp’s
inputs and output. To decrease stray capacitance, min-
imize PC board trace lengths and resistor leads, and
place external components close to the op amp’s pins.
