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 Shihab,

    I agree with David, it seems that you are trying to short +5V and -5V (even with 10k resistors) in a single node, when the switch is turned on? Can you share more info about your application?

    With regards to off leakage measurement, the setup above shows no connection to IN3, therefore switch 3 (S3 to D3) is not a valid off state. So current measured at R1 (which is connected to S3) is not a valid off leakage.

    To measure off leakage see figure 21 in the ADG1212 data sheet as a reference.
