Chip Scale Packaging
The SGM4684 is a dual, low ON-resistance, low voltage,
bidirectional, single-pole/double-throw (SPDT) CMOS
analog switch designed to operate from a single +1.8V to
+5.5V supply. Targeted applications include battery
powered equipment that benefit from low R
ON
(0.4Ω) and
fast switching speeds (t
ON
= 25 ns, t
OFF
= 28 ns).
The on resistance profile is very flat over the full analog
signal range. This ensures excellent linearity and low
distortion when switching audio signals.
The SGM4684 is a committed dual single-pole/double
-throw (SPDT) that consist of two normally open (NO) and
two normally close (NC) switches. This configuration can
be used as a dual 2-to-1 multiplexer.
SGM4684 is available in a 10-ball Chip Scale Packaging (CSP)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational
sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum
current ratings.
