NOTES: 4. This is measured with no load (open circuit output), V
ref
= 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(T
max
) – ZSE(T
min
)]/V
ref
× 10
6
/(T
max
– T
min
).
9. Full-scale error is the deviation from the ideal full-scale output (V
ref
– 1 LSB) with an output load of 10 kΩ.
10. Full-scale temperature coefficient is given by: FSETC = [FSE(T
max
) – FSE (T
min
)]/V
ref
× 10
6
/(T
max
– T
min
).
11. Zero-scale error rejection ratio (ZSE-RR) is measured by varying the V
DD
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 V
DD
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.
