ADG520x/ADG54xx Switches and Multiplexers

ADI's ADG5412 and ADG5413 contain four independent single-pole/single-throw (SPST) switches. The ADG5412 switches turn on with Logic 1. The ADG5413 has two switches with digital control logic similar to that of the ADG5412; however, the logic is inverted on the other two switches. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. The ADG5412 and ADG5413 do not have a VL pin. The digital inputs are compatible with 3 V logic inputs over the full operating supply range.

The ADG5408 and ADG5409 are monolithic CMOS analog multiplexers comprising eight single channels and four differential channels, respectively. The ADG5408 switches one of eight inputs to a common output, as determined by the 3-bit binary address lines, A0, A1, and A2. The ADG5409 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 are switched off. The on-resistance profile is very flat over the full analog input range, ensuring good linearity and low distortion when switching audio signals. High switching speed also makes the parts suitable for video signal switching.
