The ADG5408/ADG5409 are monolithic CMOS analog multiplexerscomprising eight single channels and four differentialchannels, respectively. The ADG5408 switches one of eightinputs to a common output, as determined by the 3-bit binaryaddress lines, A0, A1, and A2. The ADG5409 switches one offour differential inputs to a common differential output, asdetermined 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 are switched off. The on-resistanceprofile is very flat over the full analog input range, whichensures good linearity and low distortion when switching audiosignals. High switching speed also makes the parts suitable forvideo signal switching.Each switch conducts equally well in both directions when on,and each switch has an input signal range that extends to the powersupplies. In the off condition, signal levels up to the suppliesare blocked.The ADG5408/ADG5409 do not have a VL pins; rather, the logic powersupply is generated internally by an on-chip voltage generator.Product Highlights  Trench isolation guards against latch-up. A dielectric trench separates the P and N channel transistors thereby preventing latch-up even under severe overvoltage conditions.  Low RON.  Dual-supply operation. For applications where the analog signal is bipolar, the ADG5408/ADG5409 can be operated from dual supplies up to ±22 V.  Single-supply operation. For applications where the analog signal is bipolar, the ADG5408/ADG5409 can be operated from a single-rail power supply up to 40V.  3 V logic-compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.  No VL logic power supply required.Applications Relay replacement  Automatic test equipment  Data acquisition  Instrumentation  Avionics Audio and video switching  Communication systems
