Application Information
Power Supply Decoupling
Although not absolutely necessary, it is recommended that
all power supply lines be decoupled with 0.01µF ceramic
capacitors to ground. Decoupling capacitors should be
located as near to the amplifier terminals as possible.
Stability Considerations
HA-5195 is stable at gains > 5. Gains < 5 are covered below.
Feedback resistors should be of carbon composition located
as near to the input terminals as possible.
Wiring Considerations
Video pulse circuits should be built on a ground plane.
Minimum point to point connections directly to the amplifier
terminals should be used. When ground planes cannot be
used, good single point grounding techniques should be
applied.
Output Short Circuit
HA-5195 does not have output short circuit protection. Short
circuits to ground can be tolerated for approximately 10
seconds. Short circuits to either supply will result in
immediate destruction of the device.
Heavy Capacitive Loads
When driving heavy capacitive loads (>100pF) a small
resistor (100Ω) should be connected in series with the
output and inside the feedback loop.
