GENERAL DESCRIPTION
The ADG5412BF and ADG5413BF contain four independently The low on resistance of these switches, combined with on- controlled single-pole/single-throw (SPST) switches. The resistance flatness over a significant portion of the signal range ADG5412BF has four switches that turn on with Logic 1 inputs. make them an ideal solution for data acquisition and gain switching The ADG5413BF has two switches that turn on and two switches applications where excellent linearity and low distortion are critical. that turn off with Logic 1 inputs. Each switch conducts equally

well in both directions when on, and each switch has an input signal range that extends to the supplies. The digital inputs are 1. Switch pins are protected against voltages greater than the compatible with 3 V logic inputs over the full operating supply supply rails, up to −55 V and +55 V. range. 2. Switch pins are protected against voltages between −55 V and +55 V, in an unpowered state. When no power supplies are present, the switch remains in the 3. Overvoltage detection with digital output indicates off condition, and the switch inputs are high impedance.
