Applications Information

Power-Supply Decoupling

To achieve best results, it is highly recommended that a

decoupling capacitor be used on the IC power-supply

pins. Typical values of decoupling capacitors are 0.01FF

and 0.1FF. Use a high-quality, ceramic, surface-mount

capacitor and mount it as close as possible to the V

pins of the IC to minimize lead inductance.
