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 +1.8 to +5.5V supply, are differentiated by inverted logic, and support break-before-make switching. With 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 devices are available in a 10-pin MSOP package and a 10-pin TDFN package. 2 Key Features !
