Driving Capacitive Loads
When the AD8021 drives a capacitive load, the high frequency
response may show excessive peaking before it rolls off. Two
techniques can be used to improve stability at high frequency and
reduce peaking. The first technique is to increase the compensa-
tion capacitor, C
C
, which reduces the peaking while maintaining
gain flatness at low frequencies. The second technique is to add a
resistor, R
SNUB
, in series between the output pin of the AD8021
and the capacitive load, C
L
. Figure 15 shows the response of the
AD8021 when both C
C
and R
SNUB
are used to reduce peaking.
For a given C
L
, Figure 16 can be used to determine the value of
R
SNUB
that maintains 2 dB of peaking in the frequency response.
Note, however, that using R
SNUB
attenuates the low frequency
output by a factor of R
LOAD
/(R
SNUB
+ R
