OPA2990: About Powerup sequence

Guru 20705 points
Part Number: OPA2990

Hi Team,

 

I would like to use OPA2990S the following powerup sequence.

1. V- = -15V (VS= -15V)

2. V+ = +15V (VS=30V)

 

According to datasheet, absolute Maximum Ratings of “VS = (V+) – (V–)” is 0V to 42V.

Can I apply "V-" first?

 

And, could you please let us know a recommended powerup sequence?

(Timing of apply of V+ and V- etc.)

 

Regards,
