Overview
The ADG451BR-REEL, produced by Analog Devices Inc., is a monolithic CMOS device that comprises four independently selectable single-pole single-throw (SPST) switches. These switches are designed on an enhanced LC2MOS process, which offers low power dissipation, high switching speed, and low on-resistance of 5 Ω. The device is available in a 16-lead SOIC (Small Outline Integrated Circuit) package and is suitable for a wide range of analog switching applications.

Key Features
- Enhanced LC2MOS Process: Provides low power dissipation, high switching speed, and low on-resistance of 5 Ω.
- Single-Supply Operation: Can be operated from a single rail power supply as low as 5.0 V, and fully specified with a single 12 V power supply.
- Dual-Supply Operation: Can be operated from a dual power supply ranging from ±4.5 V to ±20 V.
- Break-Before-Make Switching: Prevents channel shorting when the switches are configured as a multiplexer (ADG453 only).
- Low Charge Injection: Minimizes transients when switching the digital inputs.
- Extended Signal Range: The signal range fully extends to the supply rails.
Applications
- Analog Signal Routing: Ideal for routing analog signals in various applications such as audio, video, and medical devices.
- Multiplexing: Suitable for use in multiplexer configurations due to its break-before-make switching action.
- Sample and Hold Circuits: Can be used in sample and hold circuits to minimize pedestal error and charge injection effects.
- Industrial and Automotive Systems: Applicable in industrial and automotive systems where reliable and low-power analog switching is required.
