1. I have application where I need to measure strain (quarter bridge three wire) of 120ohm.
2. This is power sensitive application so I am using small current to excite strain bridge isntaed of voltage.
As I can switch off current source when not required.
3. I am using 24 bit adc - ADS1248 with internal current source.
4. Is there any high precision adc with PGA > 128 ?
