HA5352/883
Fast Acquisition Dual
Sample and Hold Amplifier
Description
The HA5352/883 is a fast acquisition, wide bandwidth Dual
Sample and Hold amplifier built with the Intersil HBC-10 BiCMOS
process. This Sample and Hold amplifier offers the combination
of features; fast acquisition time (70ns to 0.01%), excellent DC
precision and extremely low power dissipation, making it ideal for
use in multi-channel systems that require low power.
The HA5352/883 comes in an open loop configuration with fully
differential inputs providing flexibility for user defined feedback. In
unity gain the HA5352/883 is completely self-contained and
requires no external components. The on-board 15pF hold
capacitors are completely isolated to minimize droop rate and
reduce the sensitivity of pedestal error. The HA5352/883 Dual
Sample and Hold is available in a 14 lead CerDIP package
saving board space while its pinout is designed to simplify layout.
