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
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 a SC70-6 package.
