HA-5320
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 latch-
free operation. For further information, please see
Application Note AN538.

NOTES:
1. Add X96 for Tape and Reel.
2. Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and
100% matte tin plate termination finish, which are RoHS
compliant and compatible with both SnPb and Pb-free soldering
operations. Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the
Pb-free requirements of IPC/JEDEC J STD-020.
