All voltages are measured with respect to ground; positive currents flow into the UBA3070 IC. The V
may not be current driven. The voltage ratings are valid provided other ratings are not violated. The current
ratings are valid provided the maximum power rating is not violated.
Human Body Model (HBM): equivalent to discharging a 100 pF capacitor through a 1.5 kΩ resistor.
Machine Model (MM): equivalent to discharging a 200 pF capacitor through a 0.75 μH coil and a 10 Ω
resistor.
