MAX4923–MAX4926
IN Bypass Consideration
For most applications, bypass IN to GND with a 1F
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.
ESD Test Conditions
The MAX4923–MAX4926 are ESD protected to ±15kV
(typ) Human Body Model on IN when IN is bypassed to
ground with a 1F ceramic capacitor as close as possi-
ble to IN.
Human Body Model
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
1.5k
Ω resistor.
