HA-5320
Data Sheet 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 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 SCRs. This allows higher speed and latchfree operation. For further information, please see
