  • RE: ADS1282: calibrate gain ads1282

    Resolved
    Hi Wivach, wivach rungshawang said: INP = +VREF / (2 x PGA) my Vref is 2.5 and gain 1. so INP = +2.5 / (2 x 1) = 1.25V and INN -1.25V. that correct? My apologies, I had made a mistake above... The differential input voltage (INP - INN) should…
