The ADG849YKSZ from Analog Devices is a 3V\/5V CMOS SPDT (single-pole, double-throw) analog switch in a tiny SC70-6 package. With ultra-low 0.5 \u03a9 typical on-resistance, 0.13 \u03a9 RON flatness, and 400 mA continuous current capability, it provides minimal signal distortion for audio routing, battery-powered systems, and relay replacement. Break-before-make switching prevents momentary shorting.<\/p>\n

Carrying 400 mA continuous current with break-before-make switching, it provides minimal distortion for audio routing, battery-powered systems, relay replacement, and portable device signal switching from 1.8V to 5.5V.","working_principle":"The ADG849YKSZ uses a CMOS transmission gate architecture with parallel N-channel and P-channel MOSFETs to achieve low and flat on-resistance across the rail-to-rail signal range. The N-channel MOSFET provides low resistance for signals near VDD, while the P-channel provides low resistance for signals near GND; together they achieve 0.5 \u03a9 typical RON with 0.13 \u03a9 flatness. The break-before-make circuitry ensures that the normally-open and normally-closed paths are never simultaneously connected, preventing signal shorts during switching transitions. The TTL\/CMOS compatible IN control pin selects between the two switch paths. Charge injection (50 pC) is minimized through balanced switch sizing. The ultra-low 1 nA supply current makes it ideal for battery-powered applications where quiescent power must be minimized.","pin_description":"\n
