Figure 10. Frequency Response with Switch On
APPLICAT ION
Figure 11 illustrates a precise, fast, sample-and-hold circuit.
An AD845 is used as the input buffer while the output
operational amplifier is an AD711. 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
.

Figure 11. Fast, Accurate Sample-and-Hold Circuit
Due to switch and capacitor leakage, the voltage on the
hold capacitor will decrease with time. T he ADG451/
ADG452/ADG453 minimizes this droop due to its low
leakage specifications. T he droop rate is further minimized
by the use of a polystyrene hold capacitor. T he droop rate
for the circuit shown is typically 30
μ
V/
μ
s.
A second switch, SW2, that 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 differ-
ential effect on the op amp AD711, which will minimize
charge injection effects. Pedestal error is also reduced by the
compensation network R
C
and C
C
. T his compensation net-
work reduces the hold time glitch while optimizing the ac-
quisition time. Using the illustrated op amps and component
values, the pedestal error has a maximum value of 5 mV over
the
±
10 V input range. Both the acquisition and settling
times are 850 ns.
