ADS8681: Max Junction Temperature

Part Number: ADS8681

Hi Team,

May we know the rated max junction temperature for ADS8681?

Thanks in advance!


Kind Regards,

Jejomar

  • Hi Jejomar,

    An estimation of the chip-junction temperature, TJ,  can be obtained from the following equation:

    TJ = TA + ( R θJA × PD ) = 25˚C + (95.7˚C/W*65mW) = 31.22°C

    where:

    TA = ambient temperature for the package ( °C )  – 25°C as an example

    RθJA = junction to ambient thermal resistance ( °C / W )  – 95.7°C/W for TSSOP package, 31.9°C/W for WQFN package

    PD = power dissipation in package (W)  – 65mW for ADS8681

    Thanks&regards,
