Product Details

The ADG411, ADG412, and ADG413 are monolithic CMOS devices comprising four independently selectable switches. They are designed on an enhanced LC2MOS process which provides low power dissipation yet gives high switching speed and low on resistance.

The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion when switching audio signals. Fast switching speed coupled with high signal bandwidth also make the parts suitable for video signal switching. CMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments.

The ADG411, ADG412, and ADG413 contain four independent SPST switches. The ADG411 and ADG412 differ only in that the digital control logic is inverted. The ADG411 switches are turned on with a logic low on the appropriate control input, while a logic high is required for the ADG412. The ADG413 has two switches with digital control logic similar to that of the ADG411 while the logic is inverted on the other two switches.

Each switch conducts equally well in both directions when on, and each has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.

PRODUCT HIGHLIGHTS

  1. Extended signal range
    The ADG411, ADG412, and ADG413 are fabricated on an enhanced LC2MOS, giving an increased signal range which extends fully to the supply rails.
  2. Ultralow power dissipation.
  3. Low RON
  4. Break-before-make switching
    This prevents channel shorting when the switches are configured as a multiplexer.
  5. Single-supply operation
    For applications where the analog signal is unipolar, the ADG411, ADG412, and ADG413 can be operated from a single-rail power supply. The parts are fully specified with a single 12 V power supply and remain functional with single supplies as low as 5 V.

APPLICATIONS

  • Audio and video switching
  • Automatic test equipment
  • Precision data acquisition
  • Battery-powered systems
  • Sample-and-hold systems
  • Communication systems
