The ADG719BRTZ-500RL7, a CMOS single-pole double-throw (SPDT) switch from Analog Devices (ADI), is a compact, low-power analog/digital signal routing solution. Designed for single-supply operation from 1.8 V to 5.5 V, it enables bidirectional signal switching with minimal distortion. This device features a break-before-make architecture, ensuring channel isolation during transitions, and supports high-speed applications with a 3 dB bandwidth exceeding 200 MHz.

Key Features

• Low On-Resistance: R_ON as low as 4 Ω (5 V), 10 Ω (3 V), and 40 Ω (1.8 V), with flat on-resistance (R_FLAT(ON) = 0.75 Ω typ.).
• High-Speed Switching: t_ON = 12 ns, t_OFF = 6 ns, enabling rapid signal path reconfiguration.
• Wide Voltage Compatibility: Operates with supply voltages from 1.8 V to 5.5 V, supporting both analog and digital interfaces.
• Ultra-Low Power: CMOS design ensures minimal static power consumption (<0.01 µW), ideal for battery-powered systems.
• Track-to-Track Operation: Ensures full rail-to-rail signal swing with no clipping.
• Temperature Range: -40°C to +125°C, suitable for automotive and industrial environments.
• Package Options: Compact 6-pin SOT-23 or 8-pin MSOP for space-constrained designs.
