3.2

The HA-2420 and HA-2425 is a monolithic circuit consisting

of a high performance operational amplifier with its output in

series with an ultra-low leakage analog switch and JFET

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. For more information,

please see Application Note AN517..
