ADG719 is a monolithic CMOS SPDT switch with features such as low power dissipation, high switching speed, low on resistance, and low leakage currents. It operates from a single-supply range of 1.8V to 5.5V, making it ideal for battery-powered instruments.
The ADG719 is a monolithic CMOS SPDT switch designed for low on‑resistance, fast switching (ton ≈ 12 ns, torr ≈ 6 ns) and low power consumption. It operates from a single 1.8 V to 5.5 V supply and is suitable for battery‑powered instruments, communication systems, audio/video routing and mechanical reed‑relay replacement.
Key specifications include a typical on‑resistance of 0.75 Ω, a maximum on‑resistance of 4 Ω, -3 dB bandwidth greater than 200 MHz, off‑isolation better than –67 dB up to 10 MHz, and automotive temperature range of –40 °C to +125 °C. The device is offered in 6‑lead SOT‑23 and 8‑lead SOIC packages with low power dissipation (282 mW SOT‑23, 315 mW SOIC).
