ESD Protection
As with all Maxim devices, ESD-protection structures are
incorporated on all pins to protect against electrostatic
discharges encountered during handling and assembly.
The COMA+ and COMA- lines have extra protection
against static electricity. Maxim’s engineers have devel-
oped state-of-the-art structures to protect these pins
against ESD of ±15kV without damage. The ESD struc-
tures withstand high ESD in all states: normal operation,
tri-state output mode, and powered down. After an ESD
event, Maxim’s E-versions keep working without latch-
up, whereas competing products can latch and must be
powered down to remove latch-up.
Human Body Model
The MAX4899E/MAX4899AE COMA+ and COMA- pins
are characterized for ±15kV ESD protection using the
Human Body Model (MIL-STD-883, Method 3015).
Figure 9a shows the Human Body Model and Figure 9b
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, which is then discharged into the device through a
1.5k
Ω resistor.
