ADG5401:  High Voltage Latch-Up Proof, Single SPST Switch

Product Details

Product Status:Recommended for New Designs

The ADG5401 is a monolithic industrial CMOS analog switch containing a latch-up immune single-pole/single-throw (SPST) switch. The switch conducts equally well in both directions when on, and has an input signal range that extends to the power supplies. In the off condition, signal levels up to the supplies are blocked.

The ultralow on resistance and on-resistance flatness of these switches make them ideal solutions for data acquisition and gain switching applications, where low distortion is critical. The latch-up immune construction, and high ESD rating, makes these switches more robust in harsh environments.

PRODUCT HIGHLIGHTS

  1. Trench isolation guards against latch-up. A dielectric trench
    separates the P and N channel transistors thereby preventing
    latch-up even under severe overvoltage conditions.
  2. Low RON.
  3. Dual-supply operation. For applications where the analog
    signal is bipolar, the ADG5401 can be operated from dual
    supplies up to ±22 V.
  4. Single-supply operation. For applications where the analog
    signal is unipolar, the ADG5401 can be operated from a
    single-rail power supply up to 40 V.
  5. 3 V logic compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.
  6. No VL logic power supply required.
  7. Available in 8-lead MSOP package.
