Power Supply Bypassing and Printed Circuit
Board Layout
The EL5420T can provide gain at high frequency, so good
printed circuit board layout is necessary for optimum
performance. Ground plane construction is highly
recommended, trace lengths should be as short as possible
and the power supply pins must be well bypassed to reduce
any risk of oscillation.
For normal single supply operation (the VS- pin is connected
to ground) a 4.7F capacitor should be placed from VS+ to
ground, then a parallel 0.1F capacitor should be connected
as close to the amplifier as possible. One 4.7F capacitor
may be used for multiple devices. For dual supply operation
the same capacitor combination should be placed at each
supply pin to ground.
For the QFN package, with exposed thermal pad, the pad
should be connected to the lowest potential, VS-, to optimize
thermal and operating performance. PCB vias should be
placed below the device’s exposed thermal pad to transfer
heat to the VS- plane and away from the device.
