SGM3799 Datasheet, PDF (1/12 Pages) SG Micro Corp – DPDT Analog Switch

SGM3799
0.5Ω, Low Voltage
Dual, DPDT Analog Switch
GENERAL DESCRIPTION
The SGM3799 is a dual, ultra low on-resistance, low
voltage, double-pole/double-throw (DPDT) CMOS analog
switch. This device is designed for low operating voltage,
high current switching of speaker output and earpiece for
cellphone applications. It can switch a balanced stereo
output.
The SGM3799 can handle a balanced microphone/
speaker/ring-tone generator in a monophone mode. It
contains a break-before-make (BBM) feature.
The SGM3799 is configured as a dual double-pole/
double-throw (DPDT) analog switch with two logic control
inputs that control two SPDT switches each. The
configuration can be used as a dual differential 2-to-1
multiplexer/demultiplexer.
The SGM3799 is available in Green TQFN-2.6×1.8-16L
package.
