AD583

The AD583 is a monolitic sample-and hold circuit consisting of a high performance operational amplifier in series with a low leakage analog switch and unity gain amplifier.An external hold capacitor,connected to the switch output,completes the sample-and-hold or track-and-hold function.

With the analog switch closed,the AD583 functions like a standard op amp;any feedback network may be connected around the device to control gain and frequency response.With the switch open the capacitor holds the output at its previous level.

The AD583 may also be used as a versatible operational amplifier with a gated output for applications such as analog switches,peak holding circuits,etc.

The AD583 has 7 features.The first one is high sample-to-hold current ratio:10^6.The second one is high slew rate is 5V/s.The third one is high bandwidth is 2MHz.The fourth one is low aperture time is 50ns.The fifth one is low charge transfer is 10pC.The sixth one is DTL/TTL compatible.The seventh one is may be used as guated Op Amp.

The AD583 has some absolute maximum ratings.The voltage between V+ and V- terminals is 40V.The differential input voltage is ±30V.The digital voltage is +8V,-15V.The output current is short circuit protected.The internal power dissipation is 30mW(derate power dissipation by 4.3mW/ above +150 ambient temperature).
