Printed Circuit Board Layout Considerations

Even though these amplifiers operate from a single

0.65V to 2.5V power supply and consume very little

supply current, it is always good engineering

practice to bypass the power supplies pins with a

0.1

μF ceramic capacitor placed in close proximity to

the VDD and VSS (or GND) pins.

Good pcb layout techniques and analog ground

plane management improve the performance of any

analog circuit by decreasing the amount of stray

capacitance that could be introduced at the op amp's

inputs and outputs. Excess stray capacitance can

easily couple noise into the input leads of the op

amp and excess stray capacitance at the output will

add to any external capacitive load. Therefore, PC

board trace lengths and external component leads

should be kept a short as practical to any of the

amplifiers’ package pins. Second, it is also good

engineering practice to route/remove any analog

ground plane from the inputs and the output pins of

these amplifiers.
