GENERAL DESCRIPTION The ADG1608/ADG1609 are monolithic CMOS analog multip- The low on resistance of these switches make them ideal solu- lexers comprising eight single channels and four differential tions for data acquisition and gain switching applications where channels, respectively. The ADG1608 switches one of eight low on resistance and distortion is critical. The on-resistance inputs to a common output, as determined by the 3-bit binary profile is very flat over the full analog input range, ensuring address lines, A0, A1, and A2. The ADG1609 switches one of excellent linearity and low distortion when switching audio four differential inputs to a common differential output, as signals. determined by the 2-bit binary address lines, A0 and A1. An CMOS construction ensures ultralow power dissipation, making EN input on both devices is used to enable or disable the device. the parts ideally suited for portable and battery-powered When disabled, all channels are switched off. instruments. Each switch conducts equally well in both directions when on PRODUCT HIGHLIGHTS and has an input signal range that extends to the supplies.
