EL5220, EL5420
Values of 150Ω and 10nF are typical. The advantage of a
snubber is that it does not draw any DC load current or
reduce the gain.
Power Supply Bypassing and Printed Circuit
Board Layout
The EL5220 and EL5420 can provide gain at high frequency.
As with any high-frequency device, good printed circuit
board layout is necessary for optimum performance. Ground
plane construction is highly recommended, lead lengths
should be as short as possible and the power supply pins
must be well bypassed to reduce the risk of oscillation. For
normal single supply operation, where the V
- pin is
S
connected to ground, a 0.1µF ceramic capacitor should be
placed from V
+ to pin to V
- pin. A 4.7µF tantalum
S
S
capacitor should then be connected in parallel, placed in the
region of the amplifier. One 4.7µF capacitor may be used for
multiple devices. This same capacitor combination should be
placed at each supply pin to ground if split supplies are to be
used.
