Hi ,
I am using PGA281 where its input stage supply is 10 V single ended (i.e VSP=10 V & VSN=0V) and
Output stage supply is 3.3V (i.e VSOP=10 V & VSON=0V) &
Logic supply is 3.3V (Different power from output stage supply).
The question I am having is " Since all these powers are coming from different stages in the circuits. It will turn on PGA in the following sequence
1) Input stage power supply will power up first
2) DVDD power will be turned on Next
3) Atlast Output stage power supply will be turned on.
Will powering up the PGA281 in this sequence damage the PGA ?? Or do we need to follow any power sequencing for PGA ?? "
Appreciate your Help at the earliest !! Thanks in Advance.
Regards,
Rajesh Kaliyaperumal
