GENERAL DESCRIPTION
The SGM4684 is a dual, low ON-resistance, low voltage,
bidirectional,
analog switch designed to operate from a single +1.8V to
+5.5V supply. Targeted applications
powered equipment that benefit from low R
fast switching speeds (t
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)
