Extended signal range. The ADG436 is a monolithic CMOS device comprising two 2 The ADG436 is fabricated on an enhanced LC MOS independently selectable SPDT switches. It is designed on an 2 process, giving an increased signal range that extends to LC MOS process, which provides low power dissipation yet the supply rails. gives high switching speed and low on resistance. 2.

CMOS construction For applications where the analog signal is unipolar, the ensures ultralow power dissipation, making the part ideally ADG436 can be operated from a single rail power supply. 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 power supplies. In the off condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.
