SGM4782
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
= 20 ns, t
OFF
= 20 ns).
The SGM4782 can handle rail-to-rail analog signals
and is available in TQFN-16 and TSSOP-16 packages.
