Figure 9 illustrates a precise, sample-and-hold circuit. An
AD845 is used as the input buffer while the output operational
amplifier is an OP07. During the track mode, SW1 is closed and
the output V
OUT
follows the input signal V
IN
. In the hold mode,
SW1 is opened and the signal is held by the hold capacitor C
H
.
Due to switch and capacitor leakage, the voltage on the hold
capacitor will decrease with time. T he ADG661/ADG662/
ADG663 minimizes this droop due to its low leakage specifica-
tions. T he droop rate is further minimized by the use of a poly-
styrene hold capacitor. T he droop rate for the circuit shown is
typically 15
μ
V/
μ
s.
A second switch SW2, which operates in parallel with SW1, is
included in this circuit to reduce pedestal error. Since both
switches will be at the same potential, they will have a differen-
tial effect on the op amp OP07 which will minimize charge
injection effects. Pedestal error is also reduced by the compensa-
tion network R
C
and C
C
. T his compensation network also re-
duces the hold time glitch while optimizing the acquisition time.
Using the illustrated op amps and component values, the pedes-
tal error has a maximum value of 5 mV over the
±
3 V input
range. T he acquisition time is 2.5 ms while the settling time is
1.85
