D = measured digital word (0 ≤D ≤127)
S = programmable gain 0.5 or 1
Vp = peak value of the measured signal
Value
I1 = S × 127 mA × D/128
V2 = 2.5 V × D/128 (maximum 2.5 V)
V3 = (2.5 V/0.4) × D/128
V4 = (2.5 V/0.4) × D/128
V5 = (2.5 V/0.4) × D/128
V6 = 8 × (Vp - Ref) × D/128
V7 = 8 × (Vp - Ref) × D/128
V4 = (2.5 V/0.4) × D/128
