I'm working on using the TI INA333 in a single 3v supply configuration. I need to create a "mid supply" (half V+) for the REF pin.
I have thought of 3 ways to do this:
- Voltage divider with resistors
- 1.5v Voltage regulator
- 1.5v Voltage reference
Here's the block diagram of the INA333:
It's going to be a battery powered device, so the solution that uses the least amount of current would be the best.
