LMKDB1102: Abs max rating of VDD

Kei Kuwahara
Expert 8710 points

Part Number: LMKDB1102

Tool/software:

Hello team,

The abs max rating of VDD is 3.63V and recommended rating is 3.6V.
There are only 0.03V margin between abs max and recommended rating.
Is the margin really this small?

Best Regards,
Kei Kuwahara

    Kuwahara-san,

    The absolute maximum is being specified as VDD + 10% - so 3.3V + 3.3V * 0.1 = 3.63V. The device can support operating voltages of 1.8V and 3.3V, so 3.63V as an absolute maximum voltage rating might seem a bit conservative, and the margin might seem small, but you must consider the width of the operating range. For the sake of the device, the supply voltage should be kept at 3.63V or less.

    Thanks,

    Michael
