GENERAL DESCRIPTIONThe SGM4684 is a dual, low on-resistance, low voltage, bidirectional, single-pole/double-throw (SPDT) CMOS analog switch designed to operate from a single 1.8V to 5.5V power supply. Targeted applications include battery powered equipment that benefit from low RON(0.4Ω) and fast switching speeds (tON = 25ns, tOFF = 28ns).

The on resistance profile is very flat over the full analog signal range. This ensures excellent linearity and low distortion when switching audio signals.

The SGM4684 is a committed dual single-pole/double-throw (SPDT) that consist of two normally open (NO) and two normally close (NC) switches. This configuration can be used as a dual 2-to-1 multiplexer.

SGM4684 is available in Green WLCSP-2.0×1.5-10B package.
