Fast switching speeds, low ON-resistance, and low power consumption make these devices ideal for singlecell battery powered applications. These highly-reliable devices operate from a single +1.6 to +3.6V supply, and are differentiated by the type and number of switches: ! ! ! 2 Key Features ! ON-Resistance: - 0.9Ω (+3V supply) - 2.5Ω (+1.8V supply) RON Matching: - 0.12Ω (+3V supply) - 0.25Ω (+1.8V supply) RON Flatness: 0.1Ω (+3V Supply) Supply Voltage Range: +1.6 to +3.6V Switching Speed: tON = 22ns, tOFF = 14ns Current-Handling: 250mA Continuous Break-Before-Make Switching (AS1753) Rail-to-Rail Signal Handling 1.8V CMOS Logic Compatible (+3V Supply) Operating Temperature Range: -40 to +85ºC Package Types: - 16-pin TQFN (3mm x 3mm) - 14-pin TSSOP ! ! ! ! ! ! ! ! AS1751 – Four normally open (NO) switches AS1752 – Four normally closed (NC) switches AS1753 – Two NO switches and Two NC switches The AS1753 supports break-before-make switching. With very low ON-resistance (RON), RON matching and RON flatness, the devices can accurately switch signals for sample and hold circuits, digital filters, and op-amp gain switching networks. The AS1751/AS1752/AS1753 digital logic input is 1.8V CMOS-compatible when using a +3V supply, and all devices can handle Rail-to-Rail signals. The devices are available in a 3mm x 3mm 16-pin TQFN package and a 14-pin TSSOP package.
