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 that connect the output pins to the load and supply pins should be as

wide as possible to minimize trace resistance.

Optimized application recommendation

It is recommended to place a 22 nF capacitor as close as possible to the supply pin. A

good decoupling will help to reduce electromagnetic interference impact.
