SGM3158 Datasheet, PDF (1/10 Pages) SG Micro Corp – 4.5Ω Dual SPDT Analog Switch in 12-pin TDFN

SGM3158
4.5Ω Dual SPDT
Analog Switch in 12-pin TDFN
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.
