The HA-2420 and HA-2425 is a monolithic circuit consisting of a high performance operational ampli er with its output in series with an ultra-low leakage analog switch and JFET input unity gain ampli er. 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 ampli er, and any of the standard op amp feedback networks may be connected around the device to control gain, requency 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 onolithic, 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 ampli ers. The device may also be used as a versatile operational ampli er with a gated output for applications such as analog switches, peak holding circuits, etc. For more information, please see Application Note AN517. The MIL-STD-883 data sheet for this device is available on request.
