HBM: human body model
All pins except headphone outputs(4)
Headphone output pins (LHP, RHP)(5)
4.
Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 k
Ω resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
5.
Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 k
Ω resistor between two pins of the device. This is done between headphone output pins, between
headphone output pins and VCC, GND. The other pins are floating.

6.
Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5
Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
