SGM4684_15 Datasheet, PDF (1/11 Pages) SG Micro Corp – SPDT Analog Switch

SGM4684
Chip Scale Packaging, Low-Voltage
0.4Ω, Dual, SPDT Analog Switch
GENERAL DESCRIPTION
The 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 R_ON (0.4Ω) and
fast switching speeds (t_ON = 25ns, t_OFF = 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.
