The HA-5330 is a very fast sample and hold amplifier designed primarily for use with high speed A/D converters. It utilizes the Intersil Dielectric Isolation process to achieve a 650ns acquisition time to 12-bit accuracy and a droop rate of 0.01μV/μs. The circuit consists of an input transconductance amplifier capable of producing large amounts of charging current, a low leakage analog switch, and an integrating output stage which includes a 90pF hold capacitor.
