Description
The HA-5320/883 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 pedestal voltage resulting from this
charge injection can be adjusted to zero by use of the offset
adjust inputs. The device includes a hold capacitor. However, if
improved droop rate is required at the expense of acquisition
time, additional hold capacitance may be added externally.
This monolithic device is manufactured using the Intersil
Dielectric Isolation Process, minimizing stray capacitance and
eliminating SCR’s. This allows higher speed and latch-free
operation. For further information, please see Application Note
AN538.
