Application Information

Power Supply Decoupling

Although not absolutely necessary, it is recommended that

all power supply lines be decoupled with 0.01

µF 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 (100

Ω) should be connected in series with the

output and inside the feedback loop.
