Low-Voltage, Quad, SPST, CMOS Analog Switches
MAX4651/MAX4652/MAX4653 quad analog switches feature on-resistance (RON) when operating from single supply. matched between switches (max) flat (0.8 max) over specified signal range. Each switch handle Rail-toRail® analog signals. Off-leakage current 0.1nA +25°C. These switches ideal low-distortion applications preferred solution over mechanical relays automated test equipment applications where current switching required. They have power requirements, require less board space, more reliable than mechanical relays. MAX4651/MAX4652/MAX4653 operate from single +1.8V +5.5V supply, making them ideal battery-powered applications. MAX4651 four normally closed (NC) switches, MAX4652 four normally open (NO) switches, MAX4653 switches. These devices available 16-pin TSSOP packages.

Applications Information
Proper power-supply sequencing recommended CMOS devices. exceed absolute maximum ratings because stresses beyond listed ratings cause permanent damage devices. Always sequence first, followed logic inputs, COM. power-supply sequencing possible, small signal diodes (D1, series with supply pins overvoltage protection (Figure Adding these diodes reduces analog signal diode drop below diode drop above GND, does affect devices' switch resistance leakage characteristics. Device operation unchanged, difference between should exceed Although required, power-supply bypassing improves noise margin prevents switching noise from propagating from supply other components. 0.1µF capacitor connected from adequate most applications.
