FILTERING
Filtering can be adjusted through selection of R
2
C
2
and
R
O
C
O
for the desired tradeoff of noise and bandwidth. Adjust-
ment of these components will result in more or less ripple
due to auto-correction circuitry noise and will also affect
broadband noise. Filtering limits slew rate, settling time, and
output overload recovery time.
It is generally desirable to keep the resistance of R
O
relatively
low to avoid DC gain error created by the subsequent stage.
This may result in relatively high values for C
O
to produce the
desired filter response. The impedance of R
O
C
O
can be
scaled higher to produce smaller capacitor values if the load
impedance is very high.
Certain capacitor types greater than 0.1
μ
F may have dielec-
tric absorption effects that can significantly increase settling
time in high-accuracy applications (settling to 0.01%). Polypro-
pylene, polystyrene, and polycarbonate types are generally
good. Certain
“
high-K
”
ceramic types may produce slow
settling
“
tails.
”
Settling time to 0.1% is not generally affected
by high-K ceramic capacitors. Electrolytic types are not
recommended for C
