SGM4157YC
SPDT 0.8Ω Analog Switch
GENERAL DESCRIPTION
The SGM4157YC is a single low on-resistance (0.8Ω),
fast single-pole double-throw (SPDT) CMOS switch. It is
designed for low operating voltage, high current
switching of speaker output for cell phone applications.
The SGM4157YC can handle a balanced microphone/
speaker/ring tone generator in a monophone mode. The
device contains a break−before−make (BBM) feature.
The control input, IN, tolerates input drive signals up to
5.5V, independent of supply voltage.
SGM4157YC is available in Green SC70-6 package.
