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,

    Thanks for the interest in our EP parts.  If you have a look at the regular ADG201A datasheet you will see a leakage plot.  Notice the log scale for leakage and as you increase in temperature the leakage increases. This is the dominant affect.  I don't have data for your conditions but my feeling is reducing the signal range may only have a minor effect in this case due to the high temperatures needed for EP parts. 

    Have a look at the ADG1212-EP as an alternative.  It has much lower leakage levels. 

    Regards,

    Eric.
