Maxim Integrated 6 MAX4736 0.6, Low-Voltage, Single-Supply, Dual SPDT Analog Switch Detailed Description Logic Inputs The MAX4736 is a low 0.8 max (at V+ = 2.7V) onresistance, low-voltage, dual SPDT analog switch that operates from a 1.6V to 4.2V single supply. CMOS switch construction allows switching analog signals that range from GND to V+. The MAX4736 logic inputs can be driven up to 3.6V, regardless of the supply voltage. For example, with a 1.8V supply, IN_ can be driven low to GND and high to 3.6V. Driving IN_ rail-to-rail minimizes power consumption. When powered from a 2.7V supply, the 0.8 max RON allows high continuous currents to be switched in a variety of applications. Analog signals that range over the entire supply voltage (V+ to GND) can be passed with very little change in onresistance (see Typical Operating Characteristics). The switches are bidirectional, so the NO_, NC_, and COM_ pins can be used as either inputs or outputs. Applications Information Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings; stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on first, followed by NO_, NC_, or COM_. Although it is not required, power-supply bypassing improves noise margin and prevents switching noise propagation from the V+ supply to other components. A 0.1F capacitor, connected from V+ to GND, is adequate for most applications. Analog Signal Levels Layout High-speed switches require proper layout and design procedures for optimum performance. Reduce stray inductance and capacitance by keeping traces short and wide. Ensure that bypass capacitors are as close to the device as possible. Use large ground planes where possible.
