SGM4717YD
GENERAL DESCRIPTION
The SGM4717YD is a dual, bidirectional, single-pole/
double-throw (SPDT) CMOS analog switch that
designed to operate from a single +1.8V to +5.5V supply.
It features high-bandwidth (300MHz) and ON-resistance
(4.5Ω TYP), targeted applications for audio switching.
SGM4717YD
features
guaranteed
on-resistance
matching (1.2Ω max) between switches and guaranteed
on-resistance flatness over the signal range (2Ω TYP).
This ensures excellent linearity and low distortion when
switching audio signals.
The SGM4717YD 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.
SGM4717YD is available in Pb-free DFN-10 package.

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.
