NOTES:

4. This is measured with no load (open circuit output), Vref = 1.25 V, range = × 2.

5. Integral nonlinearity (INL) is the maximum deviation of the output from the line between zero and full scale (excluding the effects

of zero code and full-scale errors).

6. Differential nonlinearity (DNL) is the difference between the measured and ideal 1 LSB amplitude change of any two adjacent codes.

Monotonic means the output voltage changes in the same direction (or remains constant) as a change in the digital input code.

7. Zero-scale error is the deviation from zero voltage output when the digital input code is zero.

8. Zero-scale error temperature coefficient is given by: ZSETC = [ZSE(Tmax) – ZSE(Tmin)]/Vref × 106/(Tmax – Tmin).

9. Full-scale error is the deviation from the ideal full-scale output (Vref – 1 LSB) with an output load of 10 kΩ.

10. Full-scale temperature coefficient is given by: FSETC = [FSE(Tmax) – FSE (Tmin)]/Vref × 106/(Tmax – Tmin).

11. Zero-scale error rejection ratio (ZSE-RR) is measured by varying the VDD voltage from 4.5 V to 5.5 V dc and measuring the effect

of this signal on the zero-code output voltage.

12. Full-scale error rejection ratio (FSE-RR) is measured by varing the VDD voltage from 3 V to 3.6 V dc and measuring the effect of

this signal on the full-scale output voltage.

13. Linearity is only specified for DAC codes 1 through 255.
