Protectionfor Headsets/Speakers
CM1683
Features
Product Description
•
•
The CM1683 is an L-C EMI filter array with ESD
protection, which integrates two Pi-filters (C-L-C) for
the headset speaker. The CM1683 has component
values of 100pF-3nH-100pF. The parts include ESD
protection diodes on all input/output pins, which
provide a very high level of protection for sensitive
electronic components that may be subjected to
electrostatic discharge (ESD). The ESD diodes
connected to the filter ports safely dissipate ESD
strikes of ±8kV, beyond the maximum requirement of
the IEC61000-4-2 international standard. Using the
MIL-STD-883 (Method 3015) specification for Human
Body Model (HBM) ESD, the pins are protected for
contact discharges at greater than ±15kV.

Applications
•
•
•
Headset Speaker port in mobile handsets
I/O port protection for mobile handsets, notebook
computers, PDAs, etc.
EMI filtering for data ports in cell phones, PDAs
or notebook computers
This device is particularly well suited for portable
electronics (e.g. mobile handsets, PDAs, notebook
computers) because of its small package format and
easy-to-use pin assignments. In particular, the
CM1683 is ideal for EMI filtering and protecting
speaker output lines from ESD for the headset
speaker in mobile handsets. Most speakers have
impedance of 8Ω and in order to maximize the power
output, the resistance of an EMI filter needs to be as
low as possible and the CM1683 addresses this by
having a C-L-C based EMI filter where the inductor
has less than 1Ω of resistance.
