Description
The HA5352 is a fast acquisition, wide bandwidth Dual Sam-
ple and Hold amplifier built with the Intersil HBC-10 BiCMOS
process. This Sample and Hold amplifier offers the combina-
tion of features; fast acquisition time (70ns to 0.01%), excel-
lent DC precision and extremely low power dissipation,
making it ideal for use in multi-channel systems that require
low power.
The HA5352 comes in an open loop configuration with fully
differential inputs providing flexibility for user defined feed-
back. In unity gain the HA5352 is completely self-contained
and requires no external components. The on-chip 15pF
hold capacitors are completely isolated to minimize droop
rate and reduce the sensitivity of pedestal error. The
HA5352 Dual Sample and Hold is available in a 14 lead
PDIP and 16 lead SOIC packages saving board space while
its pinout is designed to simplify layout.
