0.5Ω, High Speed, Low Voltage Analog Switch / Multiplexer

Shengbang Microelectronics Co, Ltd 

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 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.
