Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

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