1.5 Ω R, Quad SPST Switch with 1.2 V and 1.8 V JEDEC Logic Compliance

The ADG1412L is a monolithic complementary metal-oxide semiconductor (CMOS) device containing four independently selectable switches designed on an iCMOS® process. Industrial CMOS (iCMOS) is a modular manufacturing process combining high voltage CMOS and bipolar technologies.

The on-resistance profile is flat over the full analog input range, ensuring excellent linearity and low distortion (1.5 Ω typical) when switching signals.

The ADG1412L contains four independent SPST switches, and these switches are turned on with Logic 1. Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked.

An external VL supply provides flexibility for lower logic control. The ADG1412L is both 1.2 V and 1.8 V JEDEC standard compliant.
