Specifications to Consider

1. Power Supply Rejection Ratio
2. Maximum Differential Non Linearity (DNL) : DNL = Max( | (V_out(i+1) - V_out(i)) - V_{ideal LSB step} | )
3. Maximum Integral Non Linearity (INL): INL = max_0<=c<=cmax |V_out[c]-V_out[0]-c.m| where m = (V_out[c_max]-V_out[0])/c_max is the slope of the line through the end points
4. Speed, Response time
5. Operating Voltage Range

Simulations to be done

1. DNL Monte Carlo
2. INL Monte Carlo
3. PSRR for power supply extremes
4. PSRR for load extremes
5. Minimum operation voltage
