HA-5160
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.
Capacitive Loads
When driving large capacitive loads (>100pF), it is
suggested that a small resistor (≈100Ω) be connected in
series with the output of the device and inside the feedback
loop.
Stability
The phase margin of the HA-5160 will be improved by
connecting a small capacitor (>10pF) between the output
and the inverting input of the device This small capacitor
compensates for the input capacitance of the FET.
Power Supply Minimum
The absolute supply minimum is ±6V and the safe level is ±7V.
Typical Applications Suggested compensation for unity gain stability (Note 9).
