Connect a power supply to J10. Connect VSS and GND together if a single supply is required. LK1 through LK4 control the digital signals for the ADG5298. See Table 1 for the logic control truth table. 2. Supply the EVAL-ADG5298EB1Z evaluation board with a dual power source of up to ±22 V or a single supply of up to +44 V by connecting VSS and GND together.

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 EVAL-ADG5298EB1Z evaluation board. Using this evaluation board, the ADG5298 passes signals from either the source or the drain connectors. POWER SUPPLY Connector J10 provides access to the supply pins of the ADG5298. VDD, GND, and VSS on the J10 link to the appropriate pins on the ADG5298. For dual-supply voltages, the EVAL-ADG5298EB1Z evaluation board can be powered from ±5 V to ±22 V. For singlesupply voltages, the GND and VSS terminals must be connected together, and the EVAL-ADG5298EB1Z evaluation board must be powered with 8 V to 44 V. In addition, use the J10 header to supply the voltage, VL, used to control the digital logic. INPUT SIGNALS Headers connect to both the source and drain pins of the ADG5298. 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 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 can create a simple resistor capacitor (RC) filter. The ADG5298 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 board assembly uses high temperature rated components, including passives, connectors, printed circuit board (PCB) materials, and solder. By using a polyimide PCB laminate, it can handle a high glass transition temperature (TG), allowing it to maintain integrity at high temperatures where standard laminate deteriorates. The EVAL-ADG5298EB1Z evaluation board uses a Sn90Sb10 lead free solder due to its high melting point (245°C to 250°C). The EVAL-ADG5298EB1Z evaluation board also uses a nickel gold surface finish (plating) to avoid intermetallic formation between the tin in the solder and the copper PCB traces at high temperatures. In addition, the EVAL-ADG5298EB1Z evaluation board uses resistors, capacitors, and connectors rated for extended temperatures by their respective manufacturers. For further information on the EVAL-ADG5298EB1Z evaluation board construction, see the bill of materials in Table 3.

Table 1 and Table 2 show the truth table and the summary of the links. The EVAL-ADG5298EB1Z evaluation board comes with 0.1 µF decoupling capacitors populated on both the VDD and VSS power supplies, which provides sufficient decoupling for the ADG5298. However, if extra decoupling is needed due to for example, a noisy power supply, C4 and C6 can add additional decoupling capacitors. Use LK2 to LK4 to control the switches of the ADG5298. 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. SMB CONNECTORS The parallel interface of the ADG5298 is controlled manually using the link headers (LK1 to LK4), or it can be accessed using the SMB front prints (EN, A0, A1, and A2). Note that these footprints are unpopulated. Table 1.
