DATASHEET HA-5320 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.
The pedestal voltage resulting from this charge injection can be adjusted to zero by use of the offset adjust inputs.
The device includes a hold capacitor.
However, if improved droop rate is required at the ...
