Product Details

The ADG5401F main channel switch is a SPST, low on-resistance switch that features overvoltage protection, power off protection, and overvoltage detection on the source pins (S and SFB). The ADG5401F also features a protected secondary feedback channel for use with digital-to-analog converter (DAC) or amplifier outputs.

When no power supplies are present, the switch remains in the off condition, and the switch inputs are high impedance.

When powered, if the analog input signal levels on the S pin exceed VDD or VSS by a threshold voltage (VT) the switch turns off, the open-drain FF pin pulls to a logic low and a path between the D and DFB pins is switched on to prevent an open-loop condition on the amplifier output. Input signal levels up to +60 V or −60 V relative to ground are blocked, in both the powered and unpowered condition. The selectable POC pin function allows the protected switch terminal, S, to be connected to GND to minimize glitches on the output. The switch turns on with a Logic 1 input and conducts equally well in both directions. The digital input is compatible with 1.8 V logic inputs over the full operating supply range.

Product Highlights

  • Source pin is protected against voltages greater than the supply rails, up to −60 V and +60 V in both powered and unpowered states.
  • Overvoltage detection with digital output indicates operating state of switches.
  • Trench isolation guards against latch-up.
  • The ADG5401F can operate from a dual supply range of ±5 V to ±22 V or a single-supply range of +8 V to +44 V.
  • Negative channel metal oxide semiconductor (NMOS) only architecture requires 2 V headroom toward VDD and provides low RON and ultraflat RON across the VSS to VDD − 5 V signal range.
