    SGM3158

    GENERAL DESCRIPTION

    The SGM3158 is a dual, bidirectional, single-pole/double-throw (SPDT) CMOS analog switch designed to operate from a single 1.8V to 5.5V supply. It features high-bandwidth (270MHz) and low on-resistance (4.5Ω TYP), targeted applications for audio switching.

    The SGM3158 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.

    The SGM3158 is available in a Green TDFN-3×1-12L package.
