64ns Sample and Hold Amplifier
The HA5351 is a fast acquisition, wide bandwidth sample
and hold amplifier, built with the Intersil HBC-10 BiCMOS
process. This sample and hold amplifier offers a combination
of desirable features; fast acquisition time (70ns to 0.01%
maximum), excellent DC precision and extremely low power
dissipation, making it ideal for use in systems that sample
multiple signals and require low power.
The HA5351 is in an open loop configuration with fully
differential inputs providing flexibility for user defined
feedback. In unity gain the HA5351 is completely self-contained
and requires no external components. The on-chip 15pF
hold capacitor is completely isolated to minimizing droop
rate and reducing sensitivity to pedestal error. The HA5351
is available in 8 lead SOIC package for minimizing board
space and ease of layout.

NOTE: 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.
