Data Sheet April 1999

1 Microsecond Precision Sample and
Hold Amplifier

The HA-5320 was designed for use in precision, high speed
data acquisition systems.

The circuit consists of an input transconductance amplifier
capable of providing large amounts of charging current, a low
leakage analog switch,and an output integrating amplifier.The
analog switch sees virtual ground as its load; therefore, charge
injection on the hold capacitor is constant over the entire
input/output voltage range. The pedestalvoltage resulting from
this charge injection can be adjusted to zerobyuse of the offset
adjust inputs. The device includes a hold capacitor . Ho w e v er, if
improved droop rate is required at the e xpense of acquisition
time, additional hold capacitance may be added e xternally.

This monolithic device is manufactured using the Intersil
Dielectric Isolation Process, minimizing stray capacitance
and eliminating SCRs. This allows higher speed and latch­free operation. For further information, please see
Application Note AN538.
