sgm4684 chip scale packaging, low-voltage 0.4 ? , dual, spdt analog switch general description the sgm4684 is a dual, low on-resistance, low voltage, bidirectional, single-pole/double-throw (spdt) cmos analog switch designed to operate from a single 1.8v to 5.5v power supply. targeted applications include battery powered equipment that benefit from low r on (0.4 ? ) and fast switching speeds (t on = 25ns, t off = 28ns). the on resistance profile is very flat over the full analog signal range. this ensures excellent linearity and low distortion when switching audio signals. the sgm4684 is a committed dual single-pole/double -throw (spdt) that consist of two normally open (no) and two normally close (nc) switches. this configuration can be used as a dual 2-to-1 multiplexer. sgm4684 is available in green wlcsp-2.01.5-10b package. applications battery-powered, handheld, and portable equipment cellular/mobile phones laptops, notebooks, palmtops communication systems sample-and-hold circuits audio signal routing audio and video switching portable test and measurement medical equipment features low voltage operation: 1.8v to 5.5v low on-resistance: 0.4 ? (typ) low on-resistance flatness -3db bandwidth: 13mhz fast switching times t on 25ns t off 28ns rail-to-rail operation typical power consumption (< 0.01 w) ttl/cmos compatible chip scale packaging pin configuration (top view) nc1 in1 com1 no1 v + no2 in2 nc2 com2 gnd a b c 1 2 3 4 wlcsp-2.01.5-10b function table logic nc1, nc2 no1, no2 0 on off 1 off on rev. d. 2 sg micro corp www.sg-micro.com
