(...) I'd say its worth a try from the 4.3v supply from the NXT. I note that the SP03 spec. says it has a 3v regulator onboard, so its not really running from 5v anyhow. The I2C signals are open drain, so they should be ok unless their inputs won't (...) (18 years ago, 5-Dec-06, to lugnet.robotics.nxt)

It sounds like the NXT probably doesn't have enough power available to run that chip, but you might look at using a BUC (Boost-Up Converter) component to bring the 4.3V supply up to a higher level?

The NXT can also optionally apply 9V to I2C sensors on the same input/wire that is used for reading the analog values. There's a flag to set this up. I know it is accessible in RobotC and I think you should also be able to set it up via NBC. SO (...) (18 years ago, 5-Dec-06, to lugnet.robotics.nxt)

Hi Tony, (...) Nice little beast! (...) Most probably it should work. I am a bit more concerned about current consumption (80mA - not 80mAH as shown in documentation!), since the 4.3V supply can deliver 180mA for ALL seven NXT ports. You may also (...)
