AM2634: Does the VDD rail (1.2V) have a slew rate or ripple requirements?

Karla Haiat

Part Number: AM2634

I am powering the 1.2V VDD/VDDARn rails from an external regulator and need to know if they have any slew rate or ripple requirements.

Your help would be greatly appreciated

Hi,

To maintain the safe operating range of the internal ESD protection devices, TI recommends limiting the maximum slew rate of supplies to be less than 1.0E + 5 V/s.

Thanks,

Hello Nikihil,

Could you let me know where this information is outlined? I could not find this anywhere on the datasheet.

Hi,

The information is missing in datasheet currently. We will update the datasheet to reflect the same.

Thanks,
