ADG719BRT-REEL CMOS SPDT Switch from Analog Devices Inc.

The ADG719BRT-REEL is a high-performance monolithic CMOS single-pole double-throw (SPDT) switch from the renowned manufacturer Analog Devices Inc. This switch is an ideal choice for a broad range of applications, including data acquisition systems, communication systems, and audio/video switching, thanks to its low on-resistance and wide bandwidth.

One of the standout features of the ADG719BRT-REEL is its low power consumption, which makes it particularly suitable for portable and battery-powered devices. With a typical power supply range of 1.8V to 5.5V, this switch can be used in systems with varying power levels, providing design flexibility and the ability to integrate into various circuit environments.

The device comes in a compact SOT-23 package, which is not only space-saving but also ideal for high-density board designs. The small footprint of this switch does not compromise its performance; it still delivers high switching speeds and a low charge injection, which minimizes signal distortion and ensures the integrity of the signal path.

Additionally, the ADG719BRT-REEL features a built-in break-before-make switching mechanism. This means that one switch is disconnected before another connection is made, preventing any potential short circuits between the channels and protecting sensitive downstream components. This characteristic is particularly useful in multiplexing applications and when switching between different signal sources.

The switch is provided in tape and reel packaging, denoted by the "REEL" suffix in its part number, which facilitates automated assembly processes, making it a convenient option for mass production environments.

Technical highlights of the ADG719BRT-REEL include:

• Low on-resistance (typically 4 Ω)
• Single supply operation (1.8V to 5.5V)
• Fast switching times (t_ON = 20 ns, t_OFF = 10 ns typically)
• Low power dissipation
• ESD protection > 2 kV
• -3 dB bandwidth > 200 MHz

In conclusion, the ADG719BRT-REEL from Analog Devices Inc. is a versatile and efficient SPDT switch that offers excellent performance for a wide range of applications. Its low on-resistance, fast switching speeds, and low power consumption make it a top choice for designers looking to optimize their systems for both performance and power efficiency.
