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.
