DESCRIPTION
The SHC5320 is a bipolar, monolithic, sample/hold
circuit designed for use in precision, high-speed, data-
acquisition applications.
The circuit employs an input transconductance ampli-
fier 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 ca-
pacitor is constant over the entire input voltage range.
As a result, the charge offset (pedestal voltage) result-
ing 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 iso-
lation process which minimizes stray capacitance (en-
abling higher-speed operation), and eliminates latch-
up 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 tem-
perature range of –55

C to +125

age, as well as a 16-pin surface mount plastic package.
