HA1-5320-2 Datasheet 1 Microsecond Precision Sample and Hold Amplifier

Manufacturer: Intersil (now Renesas)

Overview

HA-5320 Data Sheet April 1999 File Number 2857.4 1 Microsecond Precision Sample and Hold Amplifier The HA-5320 was designed for use in precision, high speed data acquisition systems.

The circuit consists of an input transconductance amplifier capable of providing large amounts of charging current, a low leakage analog switch, and an output integrating amplifier.

The analog switch sees virtual ground as its load; therefore, charge injection on the hold capacitor is constant over the entire input/output voltage range.
