  • PGA281: Expected values mismatch

    TI Thinks Resolved
    Part Number: PGA281 Doubt about gain setting... PGA281 datasheet, page 15, figure 38: - INN = 0 - INP = 8 [Volt peak-peak] So IN (differential) = INP-INN => 8 [Volt peak-peak] - Gain = 1/8 = x0.25 VOUT = IN*0.25 = 8 [Vpeak-peak] * 0.25 = 2 [Vpeak…
