GENERAL DESCRIPTION
The SGM4727 is a dual, bidirectional, single-pole/double-
throw (SPDT) CMOS analog switches designed to operate
from
high-bandwidth (500MHz) and low ON-resistance (9Ω typ),
Targeted applications
SGM4727 features guaranteed on-resistance matching (0.3Ω
TYP) between switches and guaranteed on-resistance
flatness over the signal range (2.5Ω TYP). This ensures
excellent linearity and low distortion when switching audio
signals.
The SGM4727 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.
SGM4727 is available in a CSP-10 package.
