Note 1:
Gain is measured as a ratio of the full-scale current to I
SET
. The ratio is nominally 128.
Note 2:
Measured as voltage at mid-scale transition to ±0.024%; R
L
= 50
.
Note 3:
Measured from the rising edge of Latch Enable to where the output signal has left a 1LSB error band.
Note 4:
Glitch is measured as the largest single transient.
Note 5:
Calculated using
I = 128 x Control Amp In

TEST LEVEL CODES
TEST LEVEL
TEST PROCEDURE
100% production tested at the specified temperature.
100% production tested at T
A
= +25°C, and sample
tested at the specified temperatures.
QA sample tested only at the specified temperatures.
Parameter is guaranteed (but not tested) by design and
characterization data.
Parameter is a typical value for information purposes only.
100% production tested at T
A
= +25°C. Parameter is
guaranteed over specified temperature range.
All electrical characteristics are subject to the following
conditions:
All parameters having min/max specifications are guar-
anteed. The Test Level column indicates the specific
device testing actually performed during production
and Quality Assurance inspection. Any black section in
the data column indicates that the specification is not
tested at the specified condition.
