    SGM3799

    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 a Green TQFN-2.6×1.8-16L package.
