NOTES
1Typicals are at T
A = 25
∞C and represent most likely parametric norm. Standby current typ is measured with VCC = 3.3 V.
2Timing specifications are tested at logic levels of V
IL = 0.8 V for a falling edge and VIH = 2.2 V for a rising edge.
3I
OH for FAN_OFF guaranteed by design, not production tested.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADM1028 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
