SGM3157
4.5⦠Low Voltage SPDT
Analog Switch in 6-pin SC70
GENERAL DESCRIPTION
The SGM3157 is a single, 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.
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 a SC70-6 package.
