ELECTRICAL CHARACTERISTICS (continued)
(V
T
Note 1: All devices are 100% production tested at T
Note 2: Guaranteed by PSR test.
Note 3: Guaranteed by OUT Voltage Error test.
Note 4: Output voltage is internally clamped not to exceed 12V.
Note 5: V
Note 6: Total OUT voltage error is the sum of gain and offset voltage errors.
Note 7: Measured at I
Note 8: 6.25mV = 1/16 of 100mV full-scale voltage (C/16).
Note 9: The device will not reverse phase when overdriven.
