Supply the evaluation board with a dual power source of ±2.5 V, or a single supply from 3.0 V to 5.5 V, by connecting VSS and GND together. Connect a power supply to J10. Connect VSS and GND together if a single supply is required. Use LK1 through LK4 to control the digital signals for the ADG798. See Table 1 for the logic control truth table.

Figure 1 shows a typical evaluation setup where only a power supply and signal generator are required. Figure 2 shows the block diagram of the main components of the evaluation board. Using the EVAL-ADG798EB1Z evaluation board, the ADG798 passes signals from either the source or drain connectors. POWER SUPPLY Connector J10 provides access to the supply pins of the ADG798. VDD, GND, and VSS on J10 link to the appropriate pins on the ADG798. For dual-supply voltages, the evaluation board can be powered by ±2.5 V. For single-supply voltages, the GND and VSS terminals must be connected together, and the evaluation board must be powered with a 3.3 V to 5.5 V voltage range. Use the J10 header to supply the voltage that controls the digital logic voltage level (VL). INPUT SIGNALS Headers connect to both the source pins and the drain pins of the ADG798. Additional subminiature Version B (SMB) connector pads are available if extra connections are required. Each trace on the source and drain side includes two sets of 0805 pads, which can be used to place a load on the signal path to ground. A 0 Ω resistor is placed in the signal path and can be replaced with a user defined value. The resistor, combined with the 0805 pads, creates a simple resistor-capacitor (RC) filter. The ADG798 uses a parallel interface to control the operation of the switches. The switch operation can be manually controlled using the LK1 to LK4 switches, or an external controller can be interfaced directly to the control pins by using the SMB connector pads, if required (EN, A0, A1, and A2). See Table 1 for the logic control truth table. BOARD CONSTRUCTION The entire board assembly uses high temperature rated components, including passives, connectors, printed circuit board (PCB) material, and solder material. A polyimide PCB laminate is used due to its very high glass transition temperature (TG), which allows the board to maintain integrity at high temperature when standard laminate typically deteriorates. Sn90Sb10, Pb-free solder is used due to its high melting point (245°C to 250°C). NiAu surface finish (plating) is used on the PCB to avoid intermetallic formation between the tin in the solder with copper PCB traces at high temperatures. The resistors, capacitors, and connectors used are rated for extended temperature by their respective manufacturers. For more details on the board construction, see the bill of materials in Table 3. Rev. 0 | Page 4 of 9 EVAL-ADG798EB1Z User Guide UG-1039 JUMPER SETTINGS SWITCHES AND 0 Ω RESISTORS SMB CONNECTORS Links are used to control the ADG798 manually. Table 2 shows a summary of the links. The parallel interface of the ADG798 is controlled manually using the link headers of LK1 to LK4. The parallel interface can also be accessed using the SMB footprints: EN, A0, A1, and A2. Note that these footprints are unpopulated. Use LK2 to LK4 to control the switches of the ADG798. Position L is tied to GND and sets the logic low, and Position H is tied to VL and sets the logic high. Use LK1 to enable or disable the device. Position L is tied to GND and disables the device, and Position H is tied to VL and enables the device. DECOUPLING CAPACITORS The board comes with 0.1 μF decoupling capacitors populated on both the VDD and VSS power supplies. This provides sufficient decoupling for the ADG798. However, if extra decoupling is required due to a particular reason, such as a noisy power supply, use C4 and C6 to add additional decoupling capacitors. Table 1.
