The ADG787 is a low voltage CMOS device that contains two independently selectable single-pole, double-throw (SPDT) switches. It is designed as a general analog-to-digital switch and can also be used for routing USB 1.1 signal, cellular phones, PDAs, MP3 players, battery-powered systems, headphone switching, audio and video signal routing, communications systems, etc.
The ADG787 is a low‑voltage CMOS dual 2:1 multiplexer/demultiplexer designed for USB 1.1 signal switching. It offers two independently selectable SPDT switches with break‑before‑make action and low on‑resistance, making it suitable for battery‑powered and space‑constrained applications.
Key features include a single‑supply range of 1.8 V to 5.5 V, typical on‑resistance of 2.5 Ω, –3 dB bandwidth of 145 MHz, and availability in 10‑ball WLCSP, 10‑lead LFCSP, and 10‑lead MSOP packages. The datasheet details electrical specifications, pin functions, typical performance curves, and ordering options.
