Note 1: All devices are 100% production tested at T
A
= +25°C. All temperature limits are guaranteed by design.
Note 2: Inferred from PSRR test.
Note 3: Inferred from OUT Voltage Error test.
Note 4: Total OUT Voltage Error is the sum of the gain and offset errors.
Note 5: 6.25mV = 1/16 of 100mV full-scale sense voltage.
Note 6: Output settles to within 1% of final value.
Note 7: The device will not experience phase reversal when overdriven.
