SGM3157_15 Datasheet, PDF (1/11 Pages) SG Micro Corp – Low Voltage SPDT Analog Switch in 6-Pin SC70

GENERAL DESCRIPTION
The SGM3157 is a single, bidirectional, single-pole/
double-throw (SPDT) CMOS analog switch that is
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.
SGM3157 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.
SGM3157 is available in Green SC70-6 package.
