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
www.DataShaepept4lUic.acotimons include battery powered equipment that
benefit from low RON (0.5Ω) and fast switching speeds
(tON = 20 ns, tOFF = 20 ns).
The SGM4782 can handle rail-to-rail analog signals
and is available in TQFN-16 and TSSOP-16 packages.
