Printed circuit layout recommendations
As with any high-frequency device, a few rules must be observed when designing the PCB
so as to maximize performance.
From the most to the least important points:
●
●
●
●
●
●
Each power supply lead must be bypassed to ground with a 10 nF ceramic capacitor
and a 10 μF capacitor placed very close to the device.
To provide low inductance and low resistance common return, use a ground plane or
common point return for power and signal.
All leads must be wide and as short as possible, especially for the inputs, in order to
decrease parasitic capacitance and inductance.
Use small resistor values to decrease the time constant with parasitic capacitance.
Choose the smallest-possible component sizes (SMD).
Decrease the capacitor load at the output to avoid degrading the circuit’s stability and
cause oscillation. You can also add a serial resistor to minimize its influence.
