SGM44603 4.5 ? , 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 (4.5 ? typ), on-resistance matching (3.6 ? max) between switches and guaranteed on-resistance flatness over the signal range (3 ? 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-2.61.8-16l package . applications battery-powered systems usb 1.1 signal switching circuits communication systems portable instrumentation audio and video switching computer peripherals cell phones pdas features ? low voltage operation: 1.8v to 5.5v ? r on is typically 4.5 ? at 5v ? low on-resistance flatness ? -3db bandwidth: 300mhz ? rail-to-rail input and output operation ? typical power consumption (< 0.01 w) ? ttl/cmos compatible ? -40 to +85 operating temperature range ? available in green tqfn-2.61.8-16l package block diagram com4 no4 nc4 no3 com3 nc3 com2 no2 nc2 no1 com1 nc1 en logic in rev. a. 3 sg micro corp www.sg-micro.com
