1 Microsecond Precision Sample and Hold Amplifier
The HA-5320 was designed for use in precision, high speed
data acquisition systems.

• Gain, DC . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 x 10 V/V
• Acquisition Time. . . . . . . . . . . . . . . . . . . . . .1.0µs (0.01%)
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.
• Droop Rate. . . . . . . . . . . . . . . . . . . . . 0.08µV/µs (+25°C)
17µV/µs (Full Temperature)
• Aperture Time. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25ns
• Hold Step Error (See Glossary) . . . . . . . . . . . . . . . . . 5mV
• Internal Hold Capacitor
• Fully Differential Input
• TTL Compatible
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

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.
