DAC0830/DAC0832
Definition of Terms
(Continued)
Ideally, for the DAC0830 series, full scale is V
REF
−1LSB.
For V
REF
= 10V and unipolar operation, V
FULL-SCALE
=
10,0000V–39mV 9.961V. Full-scale error is adjustable to
zero.
Differential Nonlinearity:
The difference between any two
consecutive codes in the transfer curve from the theoretical
1 LSB to differential nonlinearity.
Monotonic:
If the output of a DAC increases for increasing
digital input code, then the DAC is monotonic. An 8-bit DAC
which is monotonic to 8 bits simply means that increasing
digital input codes will produce an increasing analog output.
