SELECTING PRACTICAL VALUES FOR INPUT
COUPLING (C C ), AVERAGING (C AV ), AND FILTERING
(C F ) CAPACITORS
common applications.
The input coupling capacitor, C C , in conjunction with the
8 k? internal input scaling resistor, determine the ?3 dB
low frequency roll-off. This frequency, F L , is equal to
Data Sheet
Note that at F L , the amplitude error is approximately ?30%
( – 3 dB) of the reading. To reduce this error to 0.5% of the
reading, choose a value of C C that sets F L at one-tenth of the
lowest frequency to be measured.
In addition, if the input voltage has more than 100 mV of dc
offset, then the ac-coupling network shown in Figure 27 should
be used in addition to C C .

Settling time is specified over the stated rms input level with the input signal increasing from zero. Settling times are greater for decreasing amplitude input signals.
