The ADG658 and ADG659 are low voltage, CMOS analog multiplexers comprised of eight single channels and four differential channels, respectively. The ADG658 switches one of eight inputs (S1S8) to a common output, D, as determined by t he 3-bit binary address lines A0, A1, and A2. The ADG659 switches one of four differential inputs to a common differential output, as determined by the 2-bit binary address lines A0 and A1. An EN i nput on both dev ices is used to enable or disable nput on bot h devices is used to enable or disable the device. When disabled, all channels are switched off.
