PCB layout recommendations

Particular attention must be paid to the layout of the PCB tracks connected to the amplifier, load, and power

supply. The power and ground traces are critical as they must provide adequate energy and grounding for

all circuits. The best practice is to use short and wide PCB traces to minimize voltage drops and parasitic

inductance. In addition, to minimize parasitic impedance over the entire surface, a multi-via technique that

connects the bottom and top layer ground planes together in many locations is often used. The copper traces

connecting the output pins to the load and supply pins should be as wide as possible to minimize trace resistance.

Decoupling capacitor

In order to ensure op-amp full functionality, it is mandatory to place a decoupling capacitor of at least 22 nF

as close as possible to the op-amp supply pin. A good decoupling helps to reduce electromagnetic interference

impact.
