MAX4651/MAX4652/MAX4653 Low-Voltage, 4Ω, Quad, SPST, CMOS Analog Switches Detailed Description V+ The MAX4651/MAX4652/MAX4653 are low on-resistance, low-voltage analog switches that operate from a single +1.8V to +5.5V supply. CMOS switch construction allows processing analog signals that are within the supply voltage range (GND to V+). D1 Applications Information Proper power-supply sequencing is recommended for all CMOS devices.
