Description: QUAD Varafet Analog Switch

Features

* rDS(ON) (Typ)
* 35Ω
* ID(OFF) (Typ)
* 10pA
* Switching Times (RL = 1kΩ) - tON
* 25ns - tOFF

Applications

* Previous applications of JFETs required the addition of diodes, in series with the gate, and then perhaps a gate-tosource referral resistor or a capacitor in parallel with the diode; therefore, at least 3 components were required to perform the switch function. The IH401A does this same job in one
