SGM3158
4.5⦠Dual SPDT
Analog Switch in 12-Pin TDFN
GENERAL DESCRIPTION
FEATURES
The SGM3158 is a dual, bidirectional, single-pole/
double-throw (SPDT) CMOS analog switch designed to
operate from a single +1.8V to +5.5V supply. It features
high-bandwidth (270MHz) and low on-resistance (4.5â¦
TYP), targeted applications for audio switching.
SGM3158 features guaranteed on-resistance matching
(0.3⦠MAX) between switches and guaranteed
on-resistance flatness over the signal range (2.3⦠TYP).
This ensures excellent linearity and low distortion when
switching audio signals.
SGM3158 is available in Green TDFN-3Ã1-12L package.
