SGM4717YD
4.5Ω, 300MHz Bandwidth,
Dual, SPDT Analog Switch
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.
