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 reduce sensitivity to pedestal error. The
HA5351 is available in 8 lead PDIP and SOIC packages for
minimizing board space and ease of layout.
