supply decoupling

▪ Place the 6.8µF capacitor within 0.75 inches of the power

▪ Placethe0.1µFcapacitorwithin0.1inchesofthepowerpin

▪ Remove the ground plane under and around the part,

especially near the input and output pins to reduce

parasitic capacitance

Evaluation Board Schematics

Evaluation board schematics and layouts are shown in

Figures 7-9. These evaluation boards are built for dual

supply operation. Follow these steps to use the board

in a single-supply application:

1. Short -Vs to ground.

2. Use C3 (6.8uF) and C4 (0.1uF), if the -VS pin of the

amplifier is not directly connected to the ground plane.
