Hi,
So, I have a sensor, 'load cell', that has the recommended excitation voltage of '5V' which I want to use with "PGA 305" or any other ADC that has same feature as this ADC. But, the problem I am facing is that the input for the sensor supplied by the PGA chip is 2.5V as "recommended operation condition".
So, is there a possible way that I can use my load cell sensor with this PGA 305 ADC, like, if I use some sort of external voltage booster at input side to my sensor or is there any other ADC IC with 5V internal supply to the weight sensor available in the "TI" ADC types.
My requirement is an ''ADC IC'' that has common supply (internally managed) to the IC itself, plus the weight sensor that I plan to use with it, so that I don't have to worry about my reference voltage change at the ADC part when the power supply is from AC and/or DC alternatively (Since, I am looking for 1g accuracy for my weight readings ).
The weight sensor(wheatstone type) I plan to use has the maximum weight reading upto 15 KG.
