(1) Boldface tested limits apply to the LJ and LCJ suffix parts only.
(2) The unit “FSR” stands for “Full Scale Range.” “Linearity Error” and “Power Supply Rejection” specs are based on this unit to eliminate
dependence on a particular V
REF
value and to indicate the true performance of the part. The “Linearity Error” specification of the
DAC0830 is “0.05% of FSR (MAX)”. This ensures that after performing a zero and full scale adjustment (see sections Zero Adjustment
and Full-Scale Adjustment), the plot of the 256 analog voltage outputs will each be within 0.05%×V
REF
of a straight line which passes
through zero and full scale.
(3) Typicals are at 25°C and represent most likely parametric norm.
(4) Tested limits are ensured to TI's AOQL (Average Outgoing Quality Level).
(5) Ensured, but not 100% production tested. These limits are not used to calculate outgoing quality levels.
(6) For current switching applications, both I
OUT1
and I
OUT2
must go to ground or the “Virtual Ground” of an operational amplifier. The
linearity error is degraded by approximately V
OS
÷ V
REF
. For example, if V
REF
= 10V then a 1 mV offset, V
OS
, on I
OUT1
or I
OUT2
will
introduce an additional 0.01% linearity error.
