SWITCHES SHOWN FOR A LOGIC 1 INPUT. Figure 2. ADG5413BF 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 PRODUCT HIGHLIGHTS well in both directions when on, and each switch has an input 1. Switch pins are protected against voltages greater than the signal range that extends to the supplies. The digital inputs are supply rails, up to 55 V and +55 V. compatible with 3 V logic inputs over the full operating supply 2. Switch pins are protected against voltages between 55 V range. 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. Under operating state of switches. normal operating conditions, if the analog input signal levels on 4. Trench isolation guards against latch-up. any switch pin exceed V DD or VSS by a threshold voltage, VT, the 5. Optimized for low on resistance and on-resistance flatness. switch turns off. Input signal levels up to +55 V and 55 V relative 6. The ADG5412BF/ADG5413BF can be operated from a to ground are blocked, in both the powered and unpowered dual-supply of 5 V up to 22 V or a single power supply condition. of 8 V up to 44 V. Rev.
