SGM3158
GENERAL DESCRIPTION
The SGM3158 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.
SGM3158 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.
SGM3158 is available in a TDFN-12 package.
4.5Ω Dual SPDT
Analog Switch in 12-pin TDFN

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.
(1)
Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum
current ratings.
