OPERATING NOTES
1. Supply Voltage Options
An on chip resistor is provided which can be used to drop the
supply voltage instead of the external 180 ohms shown in the
test circuit. The extra dissipation in this resistor reduces the
maximum ambient operating temperature to 100
°C. It is also
possible to use a 6 volt supply connected directly to pins 1 and
2 Problems with feedback on the supply line etc may occur in
this connection and RF chokes may be required in the supply
line between stages.
2. Layout P recautions
The internal decoupling capacitors help prevent high
frequency instability however normal high frequency layout
precautions are still necessary. Coupling capacitors should
be physically small and be connected with short leads. It is
most important that the ground connections are made with
short leads to a continuous ground plane.
3. Low Frequency Response
The LF response is determined by the on chip capacitors. It
can be extended by extra external decoupling on pins 5 and
1.
