I am refining a sensor board that implements an ADS1262 and a loadcell input. (I should also say that I am not an electrical engineer)
The ADS1262 uses a 5v reference, and my current setup uses multiple batteries to input above 5v and then drops that down to 5v (for the ADS ref and loadcell) and 3.3v (for my processor). I would like to simplify to a single 3.6v battery, but maintain the maximum range for the loadcell input (5v).
There are a multitude of options out there to get 5v, but I'm trying to get an optimal reading on the loadcell (which depends on the 5v ref). I'm hoping to narrow down some components to achieve this.
- It is battery powered, but stability and quality of the 5v ref is more important than power efficiency (within reason)
- I don't have any experience in running the loadcell from -2.5v-+2.5v, but I guess that is an option (my preference is to stick with the 0-5v, but thats only because I have that currently working)
- I'm assembling the prototype myself, so Ideally I'd like to avoid BGA chips
- I'm largely unconstrained on footprint size (I can use bigger chips)
It sounds like I should boost the voltage to above 5v, then drop it back down to a clean 5v.
Also, I originally posted this below, and it was suggested I ask again here.
