Off State Leakage of ADG201A-EP

I know from datasheet of ADG201A-EP that the maximum OFF state leakage of this IC with power supply =+/-15V and VD = ±14 V, VS = ∓14 V is 100nA. This leakage is too much for the circuit that I am designing. But the input signal range in my application is much less that that is given in the datasheet. Power supply to this IC is +/-15V. The input signal range will be +/- 2V. I would like to know what will be the maximum OFF state leakage for this IC over the operating temperature range of -55C to 125C for this input range? Will there be a reduction from the datasheet values?

Thanks

Shihab.

  • Hi Eric,

    I have downloaded the spice model of ADG1212 and tried some simulation. As per a basic simulation to check the leakage current ( channel to channel), I am getting large leakage currents. Following is the simulation circuit. Can you please explain why I am getting -187.5mV across R1. The leakage current seen into D1 is 1.875uA. As per datasheet the OFF Leakage over the operating temperature shall be no more than 1nA.

    Thanks,

    Shihab
