ADG5234:  High Voltage Latch-Up Proof, Quad SPDT Switches

Product Details

Product Status:Recommended for New Designs

The ADG5233 and ADG5234 are monolithic industrial CMOS analog switches comprising three independently selectable single-pole, double throw (SPDT) switches and four independently selectable SPDT switches, respectively.

All channels exhibit break-before-make switching action that prevents momentary shorting when switching channels. An EN input on the ADG5233 (LFCSP and TSSOP packages) is used to enable or disable the device. When disabled, all channels are switched off.

The ultralow capacitance and charge injection of these switches make them ideal solutions for data acquisition and sample-and-hold applications, where low glitch and fast settling are required. Fast switching speed coupled with high signal bandwidth make these devices suitable for video signal switching.

APPLICATIONS

  • Automatic test equipment
  • Data acquisition
  • Instrumentation
  • Avionics
  • Audio and video switching
  • Communication systems

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. Ultralow Capacitance and −0.6 pC Charge Injection.

  3. Dual-Supply Operation.
    For applications where the analog signal is bipolar, the
    ADG5233/ADG5234 can be operated from dual supplies
    up to ±22 V.

  4. Single-Supply Operation.
    For applications where the analog signal is unipolar, the
    ADG5233/ADG5234 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.
