SGM3003
GENERAL DESCRIPTION
The SGM3003 is a single, low ON-resistance, low voltage,
bidirectional, single-pole/double-throw (SPDT) CMOS
analog switches designed to operate from a single +1.8V to
+5.5V supply. Targeted applications include battery
powered equipment that benefit from low R
ON
(0.5Ω) and
fast switching speeds (t
ON
= 21 ns, t
OFF
= 9 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.
SGM3003 has one normally open switch and one normally
closed switch，Each switch conducts equally well in both
directions when on.
SGM3003 is available in a MSOP-8 package.
