The ADG749BKSZ-REEL7 belongs to a family of analog switches, multiplexers and demultiplexers manufactured by Analog Devices. This device is a low-voltage switch integrated with a single-pole-double-throw (SPDT) control logic. It is offered in a 3x3mm QFN-14 package and is available with a variety of package and lead options. The ADG749BKSZ-REEL7 is suitable for applications requiring a low-voltage, high-speed switch, such as in RF, battery management, and test and measurement systems.

The primary application fields for the ADG749BKSZ-REEL7 are RF, battery management, test and measurement systems, and device control. An example of its use in RF applications is as an antenna switch for mobile devices. By connecting the radio frequency input of the switch to an antenna and then routing it to the mobile device via a selectable output, the radios in the device can be switched between antennas without affecting other radios in the system. This ensures optimal signal reception and improved system performance. Additionally, the low voltage feature allows this switch to be used in low voltage power management systems.

The ADG749BKSZ-REEL7 provides single-pole-double throw (SPDT) control logic, and is controlled using a single logic control signal. The device allows logic high and low signals to be routed to either the non-selected or selected outputs. This makes the ADG749BKSZ-REEL7 suitable for use in device control applications, such as for controlling voltage regulators and power converters for power management systems. Additionally, the device is suitable for use in test and measurement systems, as it can be used to switch test points and signals between different locations.

The ADG749BKSZ-REEL7 is designed to support a wide range of input voltages, from 2V to 28V, and has a lower supply current of 1uA for standard operation and 2uA for low supply current mode. The device features a high on-resistance of 18R typical, which provides better signal isolation and minimal power loss. Additionally, it is capable of operation up to 36MHz in low voltage mode and up to 54MHz in high voltage mode. The ADG749BKSZ-REEL7 also features a low turnaround time, which makes it suitable for use in fast switching applications. The device also includes protection circuitry, which prevents damage due to static and dynamic currents.

Overall, the ADG749BKSZ-REEL7 is a robust, low voltage analog switch, multiplexer and demultiplexer that is suitable for use in a wide range of applications, including RF, power management and device control systems. It provides a high on-resistance, wide bandwidth, and fast turnaround time, which makes it suitable for use in fast-switching applications. Additionally, it features protection circuitry to prevent static and dynamic current damage, making it a reliable and safe device for use in your system.
