It is designed as a general analog-to-digital switch and can also be used for routing USB 1.1 signals. This device offers low on resistance of typically 2.5 , making the part an attractive solution for applications that require low distortion through the switch. The ADG787 comes in a 10-ball WLCSP, a tiny 10-lead LFCSP, 1 and a tiny 10-lead MSOP. These packages make the ADG787 the ideal solution for space-constrained applications. 20.0ns/DIV Each switch conducts equally well in both directions when on V = 3V p-p IN and has an input signal range that extends to the supplies. The T = 25C A = 4.2 V, PRBS 31 Figure 2. Eye Pattern 12 Mbps, VDD ADG787 exhibits break-before-make switching action. Rev.
