The ADG721, ADG722, and ADG723 are monolithic CMOS SPST switches, with a single supply voltage of 1.8 V to 5.5 V and an on resistance of 4 Ω (max).
The ADG721, ADG722, and ADG723 are monolithic CMOS SPST switches designed for low‑voltage operation (1.8 V to 5.5 V) and offered in compact 8‑lead MSOP and 3 mm × 2 mm LFCSP packages. They are suited for USB 1.1 signal routing, cell phones, PDAs, battery‑powered systems, audio/video switching, and as replacements for mechanical reed relays.
Key performance figures include a typical on‑resistance of 2.5 Ω, a –3 dB bandwidth greater than 200 MHz, turn‑on time around 20 ns and turn‑off time about 10 ns, and ultra‑low leakage currents (≈0.01 nA). The datasheet provides detailed pin descriptions, functional block diagrams, absolute maximum ratings, and typical performance curves.
