For most applications, bypass IN to GND with a 1µF
ceramic capacitor. If the power source has significant
inductance due to long lead length, take care to pre-
vent overshoots due to the LC tank circuit and provide
protection if necessary to prevent exceeding the 30V
absolute maximum rating on IN.
The MAX4923–MAX4926 are ESD protected to ±15kV
(typ) Human Body Model on IN when IN is bypassed to
ground with a 1µF ceramic capacitor as close as possi-
ble to IN.

Figure 4 shows the Human Body Model and Figure 5
shows the current waveform it generates when dis-
charged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of inter-
est that is then discharged into the device through a
1.5kΩ resistor.
