HA-2425 3.2s Sample and Hold Amplifiers

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-andhold circuit is formed. When the s.
