The ADG5412F-EP contains four independently control ed switching applications where excel ent linearity and low distortion single-pole/single-throw (SPST) switches. The ADG5412F-EP are critical. has four switches that turn on with Logic 1 inputs. Each switch
PRODUCT HIGHLIGHTS
conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. 1. Source pins are protected against voltages greater than the The digital inputs are compatible with 3 V logic inputs over the supply rails, up to −55 V and +55 V. full operating supply range. 2. Source pins are protected against voltages between −55 V When no power supplies are present, the switch remains in the and +55 V in an unpowered state. off condition, and the switch inputs are high impedance. Under 3. Overvoltage detection with digital output indicates normal operating conditions, if the analog input signal levels on operating state of switches. any Sx pin exceed V 4. Trench isolation guards against latch-up. DD or VSS by a threshold voltage, VT, the switch turns off. Input signal levels up to +55 V or −55 V 5. Optimized for low on resistance and on-resistance flatness. relative to ground are blocked, in both the powered and 6. The ADG5412F-EP can be operated from a dual supply of unpowered condition. ±5 V up to ±22 V or a single power supply of +8 V up to +44 V. The low on resistance of these switches, combined with Additional application and technical information can be found on-resistance flatness over a significant portion of the signal in the ADG5412F data sheet. range make them an ideal solution for data acquisition and gain
