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
0.1μF 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
TS1002/TS1004
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.
