FIGURE 9. Required 1.6kHz (or lower) Filtering.
FILTERING
Subsequent stages will frequently provide adequate filtering
for the INA330. However, filtering can be adjusted through
selection of R
G
C
FILTER
, and by adding a filter at V
O
for the
desired trade-off of noise and bandwidth. Adjustment of
these components will result in more or less ripple due to
auto-correction circuitry noise and will also affect broadband
noise.
It is generally desirable to keep any resistor added at V
O
(see
R
O
in Figure 9) relatively low to avoid DC gain error created
by the subsequent stage loading. This may result in relatively
high values for the filter capacitor at V
O
to produce the
desired filter response. The impedance of this filter can be
scaled higher to produce smaller capacitor values if the load
impedance is very high. Electrolytic capacitors are not rec-
ommended for the filters due to dielectric absorption effects.
