Figure 1. PWM programs V_O linearly
Figure 2. PWM programs V_O nonlinearly
Figure 3. The 8-bit PWM setting versus D = X/255. The left axis (blue curve) is V_O. The right axis (red curve) is V_O volts increment per PWM least significant bit (LSBit) increment
Figure 4. The impact of making R1_A 80% of R1_ABC. The left axis (blue curve) is V_O. The right axis (red curve) is V_O volts increment per PWM LSBit increment
