■OUTPUT VOLTAGE CALCULATION
The DAC output voltage can be calculated from the load resistance, exter nal resistors, and reference voltage
values.
VO [mV] = RL [Ω] x ( x X + x B) x VRIN [V]
X=$00 to $FF digital signal input code
B =0 (Without Pedestal voltage)
=1 (With pedestal voltage)
KFS =0.16 (Constant)
KPED =2.56 (Constant)
RL=Load resistance
