The EVAL-ADG2404 is the evaluation board for the ADG2404. The ADG2404 is an analog 4:1 multiplexer. The ADG2404 switches one of four inputs to a common output, D, as determined by the 3-bit binary address line, A0, A1, and EN. For use in multiplexer applications, switches exhibit break-before-make switching action.

Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends from VSS to VDD − 2V. When the switches are disabled, signal levels up to the supplies are blocked. The ADG2404 does not have a VL pin. The digital inputs are compatible with 1.8V logic inputs over the full-operating supply range. The on-resistance profile is very flat over the full-analog input range, which ensures good linearity and low distortion when switching audio signals.

Figure 1 in the user guide shows the EVAL-ADG2404 evaluation board. The ADG2404 is located in the center of the evaluation board and wire screw terminals are provided to connect to each of the source and drain pins. Three screw terminals power the device and a fourth terminal provides users with a defined digital logic-supply voltage, if required. Alternatively, the digital logic-supply voltage can be supplied from the ADP7142 that is on the board.

Full specifications on the ADG2404 are available in the ADG2404 data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the EVAL-ADG2404 evaluation board.
