HA5351/883
Fast Acquisition, Low Power
Sample and Hold Amplifier
Description
The HA5351/883 is a fast acquisition, wide bandwidth sam-
ple/hold amplifier built with the Intersil HBC-10 BiCMOS pro-
cess. This sample and hold amplifier offers the combination
of 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 sig-
nals and require low power. In systems with multiple chan-
nels also consider the Dual HA-5352/883 sample and hold
amplifier.
The HA5351/883 is in an open loop configuration with fully
differential inputs providing flexibility for user defined feed-
back. In unity gain the HA5351/883 is completely self-con-
tained and requires no external components. The on-board
15pF hold capacitor is completely isolated to minimizing
droop rate and reduce sensitivity to pedestal error. The
HA5351/883 is available in 8 lead CerDIP for minimum
board space and easy layout.
