HA-5330
650ns Precision Sample and Hold
Amplifier
The HA-5330 is a very fast sample and hold amplifier
designed primarily for use with high speed A/D converters. It
utilizes the Intersil Dielectric Isolation process to achieve a
650ns acquisition time to 12-bit accuracy and a droop rate of
0.01
μ
V/
μ
s. The circuit consists of an input transconductance
amplifier capable of producing large amounts of charging
current, a low leakage analog switch, and an integrating
output stage which includes a 90pF hold capacitor.
The analog switch operates into a virtual ground, so charge
injection on the hold capacitor is constant and independent
of V
IN
. Charge injection is held to a low value by
compensation circuits and, if necessary, the resulting 0.5mV
hold step error can be adjusted to zero via the Offset Adjust
terminals. Compensation is also used to minimize leakage
currents which cause voltage droop in the Hold mode.
The HA-5330 will operate at reduced supply voltages (to
±
10V) with a reduced signal range. The MIL-STD-883 data
sheet for this device is available on request.
