Radiation Hardened Fast Sample and Hold
HS-2420EH
The HS-2420EH 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 a
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 operational 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.
Specifications for Rad Hard QML devices are controlled by the
Defense Logistics Agency Land and Maritime (DLA). The SMD
numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-95669.
