The ADG4612 &ADG4613contain four independent single-pole/ single-throw (SPST) switches. The ADG4612 switches are turned on with Logic 1 on the appropriate control input. The ADG4613 has two switches with digital control logic similar to that of the ADG4612; the logic is inverted on the other two switches. Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. The ADG4613 exhibits break-before-make switching action for use in multiplexer applications.When no power supplies are present the switch remains in the OFF condition and the switch inputs are high impedance inputs. This ensures that no current flows that may damage the switch. This is very useful in application where analog signals may be present at the switch inputs before power or where the user has no control over the Power Supply Sequence.In the off condition, signal levels up to 16V are blocked. Also, if the analog input signal levels exceed VDDby VTthen the switch will turn off.The ultralow on resistance of these switches make them ideal solutions for data acquisition and gain switching applications where low on resistance and distortion is critical. The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion when switching audio signals.APPLICATIONSHot swap applicationsData acquisition systemsBattery-powered systemsAutomatic test equipmentCommunication systemsRelay ReplacementPRODUCT HIGHLIGHTSPower-Off Protection On Both S and D Pins.PSS Robustness.Overvoltage Protection up to 16 V.5.2 Ω On Resistance.16-Lead TSSOP and 3 mm × 3 mm LFCSP Packages.

The ADG467 is an octal channel protector. The channel protector is placed in series with the signal path. The channel protector protects sensitive components from voltage transience in the signal path regardless if the power supplies are present or not. For this reason, the channel protectors are ideal for use in applications where correct power sequencing cannot always be guaranteed (for example, hot insertion rack systems) to protect analog inputs.Each channel protector has an independent operation and consists of an N-channel MOSFET, a P-channel MOSFET, and an N-channel MOSFET, connected in series. The channel protector behaves just like a series resistor during normal operation, that is, (VSS+ 1.5 V) < VIN< (VDD− 1.5 V). When a channel’s analog input exceeds the power supplies (including VDDand VSS= 0 V), one of the MOSFETs switches off, clamping the output to either VSS+ 1.5 V or VDD− 1.5 V. Circuitry and signal source protection is provided in the event of an overvoltage or power loss. The channel protectors can withstand overvoltage inputs from −40 V to +40 V.The ADG467 can operate off both bipolar and unipolar supplies. The channels are normally on when power is connected and open circuit when power is disconnected. With power supplies of ±15 V, the on resistance of the ADG467 is 62 Ω typical with a leakage current of ±1 nA maximum. When power is disconnected, the input leakage current is approximately ±0.5 nA typical.The ADG467 is available in an 18-lead SOIC package and a 20-lead SSOP package.PRODUCT HIGHLIGHTSFault Protection.The ADG467 can withstand continuous voltage inputs from −40 V to +40 V. When a fault occurs due to the power supplies being turned off or due to an overvoltage being applied to the ADG467, the output is clamped. When power is turned off, current is limited to the microampere level.Low Power Dissipation.Low RON. 62 Ω typical.Trench Isolation Latch-Up Proof Construction.A dielectric trench separates the p- and n-channel MOSFETs thereby preventing latch-up.APPLICATIONSATE equipmentSensitive measurement equipmentHot insertion rack systems
