a) Feedback capacitor CNF
This relates to a low range cutoff frequency f
L
, and f
L
lowers with increasing value of the ‘C
NF
and increases with
decreasing C
NF
.
b) Oscillation compensation capacitor C
X
Signals are applied from the non-inverted NF terminal to the inverted NF terminal through the two C
NF
capacitors. It
is recommended to connect the oscillation compensation capacitor C
X
=0.01
μ
F between the floating junction of the
capacitors (minus side of C
NF
) and GND. As a rule a polyester film capacitor is recommended, but a ceramic type
may be used if a PC board shows good circuit stability.
