Electrical Overstress (EOS) Precautions

ADGM3144 is susceptible to EOS. Therefore, observe the following

precautions:

►

The ADGM3144 is an ESD-sensitive device. Observe all normal

handling precautions, including working only on static dissipative

surfaces, wearing wrist straps or other ESD control devices, and

storing unused devices in conductive foam.

►

Avoid running measurement instruments, such as digital multi-

meters (DMMs), in autorange modes. Some instruments can

generate large transient compliance voltages when switching

between ranges.

►

Use the highest practical DMM range setting (the lowest res-

olution) for resistance measurements to minimize compliance

voltages, particularly during switching.

►

Coaxial cables can store charge and lead to EOS when directly

connected to the switch. Discharge cables before connecting

directly to the switch.

►

Avoid connecting capacitive terminations directly to the switch,

as shown in Figure 74. A shunt capacitor can store a charge

that can potentially lead to hot switching events when the switch

opens or closes, affecting the lifetime of the switch.

Mechanical Shock Precautions

The ADGM3144 passes Group D mechanical shocks tests, as

detailed in Absolute Maximum Ratings. These tests validate the

robustness of the device to normal mechanical shocks.

The device should not be used if dropped. To reduce excessive me-

chanical shock and ESD events, avoid handling of loose devices,

as outlined in Figure 75.
