SGM4782
0.5Ω, High Speed, Low Voltage
Analog Switch/Multiplexer
GENERAL DESCRIPTION
The SGM4782 is high-speed, low-voltage, low
on-resistance, CMOS analog multiplexer/switch that
configured as two 4-channel multiplexers. It operates
from a single +1.8V to +4.2V power supply. Targeted
applications include battery powered equipment that
benefit from low R_ON (0.5Ω) and fast switching speeds
(t_ON = 20ns, t_OFF = 20ns).
The SGM4782 can handle rail-to-rail analog signals and
is available in Green TQFN-3×3-16L and TSSOP-16
packages.
