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,

    May I know how do you measure leakage?

    As mentioned previously, the Multisim off leakage measurement on the figure 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 and is the reason why you are having uA measurement.

    To measure leakage you may use the test setup below as a reference.

    Let me know if this helps.
