Analog Devices Inc. ADG733BRQZ Triple SPDT Switch

The ADG733BRQZ is a high-performance triple single-pole double-throw (SPDT) switch manufactured by Analog Devices Inc., designed for precision applications that require low on-resistance, low crosstalk, and fast switching speeds. This versatile component is housed in a compact 16-lead QSOP package, making it an ideal choice for space-constrained applications in both commercial and industrial environments.

Featuring a wide dual-supply voltage range from ±2.5 V to ±5.5 V or a single-supply voltage from 5 V to 16 V, the ADG733BRQZ offers flexible options for various circuit designs. This switch is capable of handling rail-to-rail analog signals, which enables it to pass signals with amplitudes close to the supply levels without distortion or significant attenuation.

The low on-resistance of the ADG733BRQZ (typically 4 ohms) ensures minimal signal loss and distortion when the switch is in the ON state, while the on-resistance flatness of less than 1.5 ohms across the full analog input range ensures consistent performance regardless of the voltage level of the signal being switched. This feature, combined with a total harmonic distortion (THD) of less than 0.02%, makes the ADG733BRQZ suitable for high-fidelity audio and precision data acquisition systems.

Switching times for the ADG733BRQZ are impressively fast, with a t_ON of 20 ns and a t_OFF of 15 ns, allowing for rapid signal routing which is critical in applications such as sample-and-hold systems, communication systems, and test equipment. The low power consumption of the device, with a typical quiescent current of just 0.1 µA, makes it an energy-efficient choice for battery-powered devices.

Moreover, the ADG733BRQZ features built-in overvoltage protection, which shields the device from momentary voltage spikes beyond the power supply levels, thereby enhancing the reliability and longevity of the switch in harsh electrical environments. Whether used in data acquisition systems, communication devices, audio and video switching, or test equipment, the ADG733BRQZ from Analog Devices Inc. offers a mix of performance, efficiency, and durability that is hard to match.
