Definition of Terms
Absolute Accuracy:
The difference between the observed
threshold voltage and the ideal threshold voltage for each
comparator. Specified and tested with 10V across the inter-
nal voltage divider so that resistor ratio matching error pre-
dominates over comparator offset voltage.
Adjust Pin Current:
Current flowing out of the reference
amplifier pin when the reference amplifier is in the linear re-
gion.
Comparator Gain:
The ratio of the change in output current
(I
) to the change in input voltage (V
) required to pro-
duce it for a comparator in the linear region.
Dropout Voltage:
The voltage measured at the current
source outputs required to make the output current fall by
10%.
Input Bias Current:
Current flowing out of the signal input
when the input buffer is in the linear region.
LED Current Regulation:
The change in output current
over the specified range of LED supply voltage (V
LED
) as
measured at the current source outputs. As the forward volt-
age of an LED does not change significantly with a small
change in forward current, this is equivalent to changing the
voltage at the LED anodes by the same amount.
Line Regulation:
The average change in reference output
voltage (V
REF
) over the specified range of supply voltage
(V
+
).
Load Regulation:
The change in reference output voltage
over the specified range of load current (I
L(REF)
).
Offset Voltage:
The differential input voltage which must be
applied to each comparator to bias the output in the linear re-
gion. Most significant error when the voltage across the in-
ternal voltage divider is small. Specified and tested with pin
6 voltage (V
RHI
) equal to pin 4 voltage (V
RLO
).
Relative Accuracy:
The difference between any two adja-
cent threshold points. Specified and tested with 10V across
the internal voltage divider so that resistor ratio matching er-
ror predominates over comparator offset voltage.
