HA-2425 - Sample and Hold Amplifiers
® Data Sheet HA-2420, HA-2425 November 19, 2004 FN2856.6 3.2µs 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-and-hold circuit is formed.
When the switch is closed, the device behaves as an o
