Note 2: All devices are 100% production tested at T
A
= +25°C. All temperature limits are guaranteed by design.
Note 3: V
OS
is calculated by applying two values of V
SENSE
(10% of full-scale range to 90% of full-scale range).
Note 4: Gain Error is calculated by applying two values of V
SENSE
(10% of full-scale range to 90% of full-scale range) and calculat-
ing the error of the slope, vs. the ideal.
Note 5: CMRR measurement is done at V
