GENERAL DESCRIPTION
The ADG5412F and ADG5413F contain four independently The low on resistance of these switches, combined with controlled single-pole/single-throw (SPST) switches. The on-resistance flatness over a significant portion of the signal ADG5412F has four switches that turn on with Logic 1 inputs. range make them an ideal solution for data acquisition and gain The ADG5413F has two switches that turn on and two switches switching applications where excellent linearity and low that turn off with Logic 1 inputs. Each switch conducts equally distortion are critical. wel in both directions when on, and each switch has an input
