MAX4751:0.9Ω, Low-Voltage, Single-Supply Quad SPST Analog Switches

The MAX4751/MAX4752/MAX4753 are low on-resistance, low-voltage, quad, single-pole/single-throw (SPST) analog switches that operate from a single +1.6V to +3.6V supply. These devices have fast switching speeds (tON = 30ns, tOFF = 25ns), handle rail-to-rail analog signals, and consume less than 1µW of quiescent power. The MAX4753 has break-before-make switching. When powered from a +3V supply, the MAX4751/MAX4752/MAX4753 feature low 0.9Ω (max) on-resistance (RON), with 0.12Ω (max) RON matching and 0.1Ω (max) RON flatness. The digital input is 1.8V CMOS compatible when using a single +3V supply. The MAX4751 has four normally open (NO) switches, the MAX4752 has four normally closed (NC) switches, and the MAX4753 has two NO and two NC switches. The MAX4751/MAX4752/MAX4753 are available in 3mm x 3mm, 16-pin QFN and 14-pin TSSOP packages.
