• Rail-to-rail signal range

The EVAL-ADG1704ARDZ is the evaluation board for the ADG1704. The ADG1704 is an analog 4:1 multiplexer and operates with a low-voltage single supply range from +1.08V to +5.5V or a low-voltage dual supply range from ±1.08V to ±2.75V. An EN input is used to disable all of the switches.

The ADG1704 is designed for small size without compromising on performance. The 2mm × 2mm land grid array (LGA) package is ideal for a broad range of applications where area is a concern.

The ADG1704 has a low on resistance of just 2.4Ω and a rail-to-rail input signal range. Each switch conducts equally well in both directions when on. The switches are turned on with a Logic 1 input on the corresponding digital control line, and the digital control inputs are 1.8V JEDEC compliant for ease of use with microcontrollers and field programmable gate arrays (FPGAs).

Figure 1 in the User Guide shows the EVAL-ADG1704ARDZ evaluation board. The ADG1704 is located in the center of the evaluation board. Wire screw terminals are provided to connect to each of the source and drain pins as well as optional Subminiature Version A (SMA) connectors. There are multiple power options on the board for providing power supplies to the evaluation board. A four terminal screw connector can be used to provide VDD, VSS, GND, and VL connections directly to the ADG1704 from an external power supply. Alternatively, on board 3.3V and 1.8V voltage regulators are supplied to provide options for VDD and VL. The on-board voltage regulators can be powered from one of three options, the external 5V supply via the screw terminal, from the 5V USB Type-C connector on the evaluation board, or using an available 5V supply from a connected SDP-K1 or compatible Arduino board.

Full specifications on the ADG1704 are available in the ADG1704 data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the EVAL-ADG1704ARDZ evaluation board.
