2 pF Off Cap, 1 pC Qinj ± 15/12 V Dual SPDT Switch
The ADG1236 is a monolithic CMOS device containing two independently selectable SPDT switches. It is designed on an enhanced CMOS process that provides low power dissipation yet gives high switching speeds, low on resistance and lower capacitance.
The ultralow capacitance and charge injection of these switches make them ideal solutions for Data Acquisition and Sample/Hold applications where low glitching and fast settling is required.
Fast switching speed coupled with high signal bandwidth also make the part suitable for video signal switching. CMOS construction ensures ultralow power dissipation making the parts ideally suited for portable and battery powered instruments. Each switch conducts equally well in both directions when ON and has an input signal range which extends to the supplies. In the OFF condition, signal levels up to the supplies are blocked. All switches exhibits break-beforemake switching action for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.
