64ns Sample and Hold Ampli鏗乪r
The HA5351 is a fast acquisition, wide bandwidth sample
and hold ampli鏗乪r, built with the Intersil HBC-10 BiCMOS
process. This sample and hold ampli鏗乪r 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 con鏗乬uration with fully
differential inputs providing 鏗俥xibility for user de鏗乶ed
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.
