0.8Ω, Low-Voltage, Single-Supply SPDT Analog Switch in SC70
General Description
The MAX4714 is a low on-resistance, low-voltage single-pole/double-throw (SPDT) analog switch that operates from a single +1.6V to +3.6V supply. The MAX4714 has break-before-make switching. This device also has fast switching speeds (t ON = 18ns max, tOFF = 12ns max). When powered from a +3V supply, the MAX4714 features 0.8Ω max on-resistance (RON), with 0.18Ω max RON matching and flatness. The digital logic input is 1.8V CMOS compatible when using a single +3V supply. The MAX4714 is pin compatible with the MAX4599 and is available in a 6-pin SC70 package. o Low RON 0.8Ω max (+3V Supply) 2.5Ω max (+1.8V Supply) o 0.18Ω max RON Flatness (+3V Supply) o +1.6V to +3.6V Single-Supply Operation o Available in 6-Pin SC70 Package o Fast Switching: tON = 18ns max, tOFF = 12ns max o 1.8V CMOS Logic Compatible (+3V Supply) o Pin Compatible with MAX4599 o Guaranteed Break-Before-Make
