Key Features
- Ultralow Capacitance and Charge Injection: Ideal for data acquisition and sample-and-hold applications where low capacitance and charge injection are critical.
- Low On-Resistance: Typical on-resistance of 120 Ω, ensuring minimal signal attenuation.
- High Signal Integrity: The switches conduct equally well in both directions when on, and block signal levels up to the supplies when off.
- Dual Supply Operation: Operates with dual supplies (VDD and VSS), allowing for a wide range of analog signal levels.
- Break-Before-Make Switching (ADG1213): Ensures that one switch is turned off before the other is turned on, preventing signal overlap and making it suitable for multiplexer applications.
Applications
- Data Acquisition Systems: The low capacitance and charge injection make these switches ideal for data acquisition systems where signal integrity is crucial.
- Sample-and-Hold Circuits: Suitable for sample-and-hold applications due to their low on-resistance and minimal signal distortion.
- Multiplexer Applications: The ADG1213 with its break-before-make switching action is particularly useful in multiplexer configurations.
- Audio and Video Switching: Can be used in audio and video switching applications where low distortion and high signal fidelity are required.
