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)
