The ADG5408-EP/ADG5409-EP are monolithic CMOS analog multiplexers comprising eight single channels and four differential channels， respectively. The ADG5408-EP switches one of eight inputs to a common output， as determined by the 3-bit binary address lines， A0， A1， and A2. The ADG5409-EP 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 enables or disables the device. When EN is disabled， all channels switch off. The on-resistance profile is very flat over the full analog input range， which ensures good linearity and low distortion when switching audio signals. High switching speed also makes the parts suitable for video signal switching. Each switch conducts equally well in both directions when on， and each switch has an input signal range that extends to the power supplies. In the off condition， signal levels up to the supplies are blocked.
