PC Board Layout

The frequency response of this circuit depends greatly on

the care taken in designing the PC board. The use of low

inductance components such as chip resistors and chip

capacitors is strongly recommended, while a solid

ground plane is a must!

Attention should be given to decoupling the power supplies.

A large value (10µF) tantalum in parallel with a small value

(0.1µF) chip capacitor works well in most cases.

Keep input and output traces as short as possible, because

trace inductance and capacitance can easily become the

performance limiting items.
