**ADG722BRM: A Comprehensive Technical Overview of Analog Devices' SPDT CMOS Switch**

The **ADG722BRM** from Analog Devices represents a highly integrated, single-pole double-throw (SPDT) monolithic CMOS switch, engineered to deliver exceptional performance in a compact footprint. Designed for a broad range of applications, from portable instrumentation to communication systems, this switch combines low power consumption with high switching speed and superb linearity.

Housed in a space-saving **10-lead MSOP package**, the ADG722BRM is optimized for applications where board space is at a premium. A key feature of this device is its **1.8 V to 5.5 V single-supply operation**, making it directly compatible with low-voltage logic and modern microcontrollers, thereby simplifying system design and power management. The switch also features **break-before-make switching action**, a critical function that prevents momentary shorting between the two channels during switching transitions, thus protecting downstream circuitry.

The electrical performance of the ADG722BRM is characterized by its **low on-resistance (RON) of just 0.5 Ω** (typical at 5 V supply) and remarkably flat on-resistance across the input signal range. This low and consistent RON ensures minimal signal attenuation and distortion, which is paramount for maintaining signal integrity in precision analog and audio paths. Furthermore, the device exhibits an impressive **-3 dB bandwidth of 200 MHz**, enabling it to handle high-frequency signals effectively.

Another significant advantage is its **ultra-low power consumption**, drawing less than 0.01 μA of supply current, which is virtually negligible. This makes it an ideal candidate for battery-powered and always-on applications. The CMOS construction also provides **high off-isolation and low crosstalk**, effectively isolating the switched signals from each other to prevent unwanted interference.

The digital interface is designed for ease of use, controlled by a single logic input that is **TTL/CMOS compatible**. The robust **latch-up immune construction** ensures the device remains reliable even in harsh electrical environments.

**ICGOODFIND:** The ADG722BRM stands out as a superior solution for signal routing tasks, masterfully balancing a tiny form factor with robust electrical characteristics. Its combination of **very low on-resistance, wide bandwidth, and minimal power consumption** makes it an exceptionally versatile and reliable component for modern electronic design, from medical devices to automated test equipment.
