SGM44600
GENERAL DESCRIPTION
The SGM44600 is a dual, high-speed, low-voltage,
double-pole/double-throw (DPDT) CMOS analog
switch that is designed to operate from a single 1.8V
to 5.5V power supply. It features high-bandwidth
(300MHz) and low ON-resistance (4Ω TYP), targeted
applications for audio switching.
The SGM44600 consists of four SPDT switches. The
configuration can be used as a bidirectional quad
2-channel multiplexer/demultiplexer with a single
switch-enable (IN) input.
SGM44600 can handle rail-to-rail analog signals and is
available in Pb-free TQFN-16(3mm
×
3mm) package.
