SGM4727
GENERAL DESCRIPTION
The SGM4727 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 (500MHz) and low ON-resistance (9Ω typ),
Targeted applications
for
audio switching.

Voltage Operation : 1. 8 V to 5. 5 V
On-Resistance: 9Ω (typ) at 5.0V
High Bandwidth: 500 MHz
Fast Switching Time

High Off-Isolation: 66dB at 10MHz
Low Crosstalk: 105dB at 10MHz
Rail-to-Rail Operation
TTL/CMOS Compatible
Break-Before-Make Switching
Extended Industrial Temperature Range:
–40°C to 85°C
Chip-Scale Package
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.

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.

Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum
current ratings.
