SGM4717EP
GENERAL DESCRIPTION
The SGM4717EP is a dual, bidirectional, single-pole/double
-throw (SPDT) CMOS analog switches designed to operate
from a single +1.8V to +5.5V supply. It features
high-bandwidth (300MHz) and low ON-resistance (4.5Ω
typ), Targeted applications
for
audio switching.

High Off-Isolation: 57dB at 10MHz
Low Crosstalk: 99dB at 10MHz
Rail-to-Rail Operation
TTL/CMOS Compatible
Break-Before-Make Switching
Extended Industrial Temperature Range:
–40°C to 85°C
WQFN-10 Packages
SGM4717EP features guaranteed on-resistance matching
(0.3Ω max) between switches and guaranteed on-resistance
flatness over the signal range (2.3Ω TYP). This ensures
excellent linearity and low distortion when switching audio
signals.
The SGM4717EP 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.
SGM4717EP is available in WQFN-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.
