The user inquired about applying negative DC signals at S1 and S2 of the ADG419 switch and switching between them using a control signal. The engineer confirmed that the device can handle signals within the Vss to Vdd range, requiring dual supplies greater than +/-5V. The user's +/-12V supplies and 3.3V control signal are within the specified limits, ensuring the ADG419 will function correctly.

Hello,
Can i give both negative dc signal at S1 and S2 of the switch and switch between them using control signal?
As long as your signals at S1 and S2 are within Vss to Vdd signal range, you should have no problem using the ADG419. Just bear in mind that you will need to power up the ADG419 with dual supplies (greater than +/-5 V, as we cannot guarantee normal operation with lower supplies), and that this part is specified with VL = 5 V, and VIN = 5 V.
