The EVAL-ADG6436EBZ is the evaluation board for the ADG6436. The ADG6436 is an analog multiplexer, containing two independently selectable single-pole, double throw (SPDT) switches. An EN input is used to disable all of the switches. For use in multiplexer applications, both switches exhibit break-before-make switching action. Each channel conducts equally well in both directions when on, and each switch has an input signal range that extends from V_SS to V_DD − 2 V. When switches are disabled, signal levels up to the supplies are blocked. The digital inputs are compatible with 5 V, 3.3 V, and 1.8 V logic inputs without the requirement for a separate digital logic supply pin. The on-resistance profile is exceptionally flat over the full analog input range, which ensures good linearity and low distortion when switching audio signals.

Figure 1 shows the EVAL-ADG6436EBZ evaluation board. The ADG6436 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 ADG6436 are available in the ADG6436 data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the EVAL-ADG6436EBZ evaluation board.
