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.
