ADG819/ADG820 is a monolithic CMOS SPDT switch that is designed on a submicron process to provide low power dissipation, high switching speed, low on resistance and high reliability.
The ADG819 and ADG820 are monolithic CMOS SPDT switches designed for low power consumption, high switching speed, and low on‑resistance. They operate from a single 1.8 V to 5.5 V supply and are suitable for battery‑powered, portable instruments and a range of applications such as power routing, communication systems, and relay replacement.
Both devices are offered in 6‑lead SOT‑23, 8‑lead uSOIC, and (for ADG819) 2 × 3‑bump MicroCSP packages. Detailed specifications include on‑resistance, leakage currents, switching times, and absolute maximum ratings, with automotive temperature support from –40 °C to +125 °C.
