SGM44603

SGM44603 4.5Ω, High Speed, Low Voltage Quad, SPDT Analog Switch GENERAL DESCRIPTION The SGM44603 is a high-speed, low-voltage, quad single-pole/double-throw (SPDT) CMOS analog switch multiplexer that is designed to operate from a single +1.8V to +5.5V power supply. SGM44603 features guaranteed on-resistance (4.5Ω TYP), on-resistance matching (3.6Ω MAX) between switches and guaranteed on-resistance flatness over the signal range (3Ω TYP). This ensures excellent linearity and low distortion when switching audio signals. Fast switching speed, coupled with high signal bandwidth (300MHz), also makes the parts suitable for video signal switching. CMOS construction ensures ultra low power dissipation, making the parts ideally suited for portable and battery powered instruments. SGM44603 is available in Green TQFN-2.6×1.8-16L package.
