1 / 14 page General Description The MAX4747–MAX4750 low-voltage, quad single-pole single-throw (SPST)/dual single-pole/double-throw (SPDT) analog switches operate from a single +2V to +11V supply and handle rail-to-rail analog signals. These switches exhibit low leakage current (0.1nA) and consume less than 0.5nW (typ) of quiescent power, making them ideal for battery-powered applications. When powered from a +3V supply, these switches fea- ture 50 Ω (max) on-resistance (RON), with 3.5Ω (max) matching between channels and 9 Ω (max) flatness over the specified signal range. The MAX4747 has four normally open (NO) switches, the MAX4748 has four normally closed (NC) switches, and the MAX4749 has two NO and two NC switches. The MAX4750 has two SPDT switches. These switches are available in 14-pin TSSOP, 16-pin TQFN (4mm x 4mm), and 16-bump WLP packages. This tiny chip-scale pack- age occupies a 2mm 2mm area and significantly reduces the required PC board area.
