Overview
The ADG787BRMZ-REEL, produced by Analog Devices Inc., is a low voltage, CMOS device that contains two independently selectable, single-pole, double-throw (SPDT) switches. This device is designed as a general analog/digital switch and is also suitable for routing USB 1.1 signals. It features low on resistance, typically 2.5 Ω, making it an attractive solution for applications requiring low distortion through the switch. The ADG787 is available in several compact packages, including a 10-ball WLCSP, a 10-lead LFCSP, and a 10-lead MSOP, making it ideal for space-constrained applications.
