The ADG821/ADG822/ADG823 are low-power, low-voltage, high-switching-speed monolithic CMOS SPST switches.
The ADG821, ADG822, and ADG823 are monolithic CMOS SPST switches designed for low power dissipation, 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 instruments, power routing, and signal routing in communication and data‑acquisition systems.
The devices are offered in an 8‑lead MSOP package and meet automotive temperature specifications (‑40 °C to +125 °C). The datasheet provides detailed electrical characteristics, absolute maximum ratings, pin configuration, and ordering information for each part number.
