HA5351

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.
