Radiation Hardened Fast Sample and Hold
Description
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-andhold 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.
