Power Supply Bypassing Printed Circuit Board
Layout
As with any modern operational amplifier, a good printed circuit
board layout is necessary for optimum performance. Lead
lengths should be as short as possible. The power supply pin
must be well bypassed to reduce the risk of oscillation. For
normal single supply operation, a single 4.7µF tantalum
capacitor in parallel with a 0.1µF ceramic capacitor from VS+ to
GND will suffice.
Printed Circuit Board Layout
For good AC performance, parasitic capacitance should be
kept to minimum. Use of wire wound resistors should be
avoided because of their additional series inductance. Use of
sockets should also be avoided if possible. Sockets add
parasitic inductance and capacitance that can result in
compromised performance.
