10.1 Layout Guidelines
For best operational performance of the device, TI recommends good printed circuit board (PCB) layout
practices. Low-loss, 0.1-µF bypass capacitors should be connected between each supply pin and ground, placed
as close to the device as possible. A single bypass capacitor from V+ to ground is applicable for single-supply
applications.
10.2 Layout Example
Place components close to
device and to each other to
VS+
reduce parasitic errors
Run the input traces as
far away from the supply
lines as possible
