ADC12QJ1600-EP: Guidance for driving INA, INB, INC, IND of an unpowered device

Jesse Haynes-Lewis

Part Number: ADC12QJ1600-EP

Is there any guidance towards driving the RF inputs of the device while the device is powered down? Specifically looking for max RF input power into an unpowered device, I don't see anything in the datasheet regarding this.

Thanks,

Jesse

Hi Jesse,

Typically our recommendations would be to stay within the abs max of the device, even when the device is powered down.

I am confirming internally for you.

Please give me a few days to update you.

Thanks,

Rob

Hi Jesse,

I have a correct myself. Our recommendation is to use the Recommended Operating Conditions table, not ABS MAX table for cold sparing.

Regards,

Rob
