Note 1: All devices are 100% production tested at T
A
= +25°C. All temperature limits are guaranteed by design.
Note 2: Guaranteed by PSR test.
Note 3: Guaranteed by OUT Voltage Error test.
Note 4: Guaranteed by Gain Accuracy test. Output voltage is internally clamped not to exceed 12V.
Note 5: Total OUT Voltage Error and Full-Scale Accuracy are the sum of gain and offset voltage errors.
Note 6: Measured at I
OUT
= -500µA (R
LOAD
= 4kΩ for gain of +20V/V, R
LOAD
= 10kΩ for gain of +50V/V, R
LOAD
= 20kΩ for gain of
+100V/V).
Note 7: +6.25mV = 1/16 of +100mV full-scale voltage.
Note 8: The device will not experience phase reversal when overdriven.
Note 9: All comparator tests are done with V
RS+
= +12V.
Note 10: V
PULL-UP
is defined as an externally applied voltage through a resistor to pull up the comparator output.
Note 11: V
OS
is extrapolated from the gain accuracy test.
