Hi,
We are using the ADG1439 Multiplexor (Analog Switchs).

We are supplying it with Vdd = +24V, Vss = -4V (and Gnd = 0V).

Do you know what will be the Analog switch resistance?

Fig 9, Page 13 of the datasheet looks relevant, but does not specifically address our exact Vdd and Vss.

ADG1439 datasheet:
--- Updated ---

VD and VS will be anywhere between -4V and +24V

so,

I´d expect R_ON to be 6 ... 10 Ohms. extrapolated from Fig. 9.

Hi Thanks,
Would you also say that from page 3, the maximum switch_ON or OFF delay is 185ns?
In other words, after switching it off, we can be sure that is completely OFF after 185ns?
Ditto for switching ON?
 

Dynamic IL current is specified for 50 MHz shift register clock. MHz switching is obviously not considered in the datasheet.
