Ordering Information
The HS-2420RH is a radiation hardened monolithic circuit
consisting of a high performance operational amplifier with
its output in series with an ultra-low leakage analog switch
and MOSFET input unity gain amplifier.
With an external hold capacitor connected to the switch output,
a versatile, high performance sample-and-hold or track-and-
hold circuit is formed. When the switch is closed, the device
behaves as an operation amplifier, and any of the standard op
amp feedback networks may be connected around the device
to control gain, frequency response, etc. When the switch is
opened the output will remain at its last level.
Performance as a sample-and-hold compares very favorably
with other monolithic, hybrid, modular, and discrete circuits.
Accuracy to better than 0.01% is achievable over the
temperature range. Fast acquisition is coupled with superior
droop characteristics, even at high temperatures. High slew
rate, wide bandwidth, and low acquisition time produce
excellent dynamic characteristics. The ability to operate at
gains greater than 1 frequently eliminates the need for
external scaling amplifiers.
The device may also be used as a versatile operational
amplifier with a gated output for applications such as analog
switches, peak holding circuits, etc.
