The ADG1308 and ADG1309 are monolithic analog multi-plexers consisting of eight single channels and four differential channels, respectively. The ADG1308 switches one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1, and A2. The ADG1309 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 input on both devices is used to enable or disable the device. When disabled, all channels are switched off.
When the switches are on, each switch conducts equally well in both directions and has an input signal range that extends to the power supplies. In the off condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action for use in multiplexer applications. Inherent in the design is the low charge injection for minimum transients when switching the digital inputs.
Fast switching speed coupled with high signal bandwidth makes the parts suitable for video signal switching. CMOS construction ensures ultra low power dissipation, making the parts ideally suited for portable and battery-powered instruments.
