Other Parts Discussed in Thread: REF3012, INA125, ADS1235, OPA388, ADS1261
Hello people!
With ADS1262 PGA set on Gain 32, the full scale is 78mV, so my load cell -with its 20mV max output- isn't able to exploit ADS capabilities.
I have two solutions:
I could set an external Vref by a REF3012 so 1.25V/32=37mv (fine!).
I can use a load cell amplifier as TI INA125, using internal Vref as INA125 ref.
Each solution is quite affordable (I need only 3-4 components for a year, so a money difference is not significant) and seems to goal my needings but... what do you suggest? Does using an external amplifier make harder system tare?
Thanks very much and have a nice day!
