DESCRIPTION

The SHC5320 is a bipolar, monolithic, sample/hold
circuit designed for use in precision, high-speed, data­acquisition applications.

The circuit employs an input transconductance ampli­fier capable of providing large amounts of charging
current to the holding capacitor, thus enabling fast
acquisition times. It also incorporates a low leakage
analog switch and an output integrating amplifier with
input bias current optimized to assure low droop rates.
Since the analog switch always drives into a load at
virtual ground, charge injection into the holding ca­pacitor is constant over the entire input voltage range.
As a result, the charge offset (pedestal voltage) result­ing from this charge injection can be adjusted to zero
by use of the offset adjustment capability. The device
includes an internal holding capacitor to simplify ease
of application; however, provision is also made to add
additional external capacitance to improve the output
voltage droop rate.

The SHC5320 is manufactured using a dielectric iso­lation process which minimizes stray capacitance (en­abling higher-speed operation), and eliminates latch­up associated with substrate SCRs. The SHC5320KH,
KP, and KU feature fully specified operation over the
extended industrial temperature range of –40°C to
+85°C, while the SHC5320SH operates over the tem­perature range of –55°C to +125°C. The device re­quires ±15V supplies for operation, and is packaged in
a reliable 14-pin ceramic or plastic dual-in-line pack­age, as well as a 16-pin surface mount plastic package.

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown

< +150°C

A

recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degrada­tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
