The ADG619BRM: A High-Performance Analog Switch for Precision Applications

The ADG619BRM is a monolithic CMOS analog switch designed for high-speed, low-power applications. Manufactured by Analog Devices, this IC delivers low on-resistance (5Ω typical) and fast switching times, making it ideal for signal routing, audio/video systems, and test equipment. Its ±2.7V to ±5.5V dual-supply operation ensures compatibility with a wide range of systems, while the 2.7V to 5.5V single-supply option adds flexibility.

Key Features of the ADG619BRM

1. Low Power Consumption: The ADG619BRM consumes just 0.1μA (max) in standby mode, making it perfect for battery-powered devices.

2. High Bandwidth (200MHz): Ensures minimal signal distortion in high-frequency applications.

3. Break-Before-Make Switching: Prevents signal shorting during transitions.

4. TTL/CMOS-Compatible Logic Inputs: Simplifies interface with digital controllers.

5. Small 10-Lead MSOP Package: Saves PCB space in compact designs.

Applications of the ADG619BRM

- Audio/Video Signal Routing: Ensures clean switching in multimedia systems.

- Automated Test Equipment (ATE): Provides reliable signal multiplexing.

- Data Acquisition Systems: Enables low-noise channel selection.

- Medical Instrumentation: Supports high-precision measurements.

- Portable Electronics: Extends battery life with ultra-low power draw.

Why Choose the ADG619BRM?

Engineers favor the ADG619BRM for its exceptional performance-to-cost ratio. Unlike mechanical relays, it offers noiseless, wear-free operation and long-term reliability. Its ESD protection (4kV HBM) further enhances durability in harsh environments.

Design Considerations

For optimal performance:

- Use decoupling capacitors near power pins.

- Ensure proper grounding to minimize crosstalk.

- Avoid exceeding maximum ratings (e.g., 30mA continuous current).
