Application Hints
OPERATING NOTES
The signal source is usually capacitively coupled to the in-
put. At higher frequencies a 0.001
m
F input capacitor (C1) is
usually sufficient, with larger values used at the lower fre-
quencies. If the input signal is likely to be interrupted, it may
be desirable to connect a 100 k
X
resistor between one in-
put and ground to stabilize the device. In the single-ended
mode, it is preferable to connect the resistor to the unused
input. In the differential mode, the resistor can be connected
to either input. The addition of the 100 k
X
pulldown resistor
causes a loss of input sensitivity, but prevents circuit oscilla-
tions under no signal (open circuit) conditions. In addition, in
the single ended mode, a capacitor of 0.001
m
F (C2) should
be connected between the unused input and the ground
plane to provide a good high frequency bypass. The capaci-
tor should be made larger for lower frequencies.
The input waveform may be sinusoidal, but below about
20 MHz the operation of the circuit becomes dependent on
the slew rate of the input rather than amplitude. A square
wave input with a slew rate of greater than 20 V/
m
s will
permit correct operation down to lower frequencies, provid-
ed the proper input coupling capacitor is provided.
For regulated mode operation connect V
S
to V
REG
to en-
sure proper operation (see Typical Application diagram).
