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 RON (0.5Ω) and fast switching speeds
(tON = 20 ns, tOFF = 20 ns).
tOFF 20 ns
− Low Crosstalk: -108 dB at 1 MHz
− Typical Power Consumption (<0.01 µW)
− TTL/CMOS Compatible
The SGM4782 can handle rail-to-rail analog signals
and is available in TQFN-16 and TSSOP-16 packages.
− Rail-to-Rail Input and Output Operation
− Break-Before-Make Switching
− Extended Industrial Temperature Range:
–40°C to +85°C
