The ADG2188 is specified to operate in single-supply mode at 12 V ± 10% operation. It is also specified to operate at ±5 V dual supply. To apply these supplies to the evaluation board, adhere to the following guidelines: • • The VL pin provides the digital supply for the ADG2188 and all digital circuitry on the board. This supply can be applied externally or the USB port can power the digital circuitry (Link 5 inserted). Note that in this case, the logic supply power is 3.3 V. The positive supply voltage (for example, 12 V) is applied between the AVDD and AGND inputs of the ADG2188 evaluation board. Note the maximum single supply the ADG2188 can handle is 15 V. In this case, the AVSS input must equal 0 V. The negative supply (for example, −5 V) is applied between the AVSS and AGND inputs for the negative supply (VSS) of the ADG2188. Note that the maximum voltage between AVDD and AVSS is 15 V. Both analog GND and digital GND inputs are provided on the board. The AGND and DGND planes are connected at one location on the evaluation board close to the ADG2188 It is recommended not to connect AGND and DGND elsewhere in the system to avoid ground loop problems. Each supply is decoupled to the relevant ground plane with 10 µF and 0.1 µF capacitors. Each device supply pin is also decoupled with a 10 µF and 0.1 µF capacitor pair to the relevant ground plane. LINK OPTIONS There are a number of links and switch options on the evaluation board that must be set for the required operating setup before using the board. The functions of these link options are described in Table 1. Table 1. Link Functions Link No. LK1 LK2 LK3 LK4 LK5 Function This link chooses the first LSB bit of the chip address on the USB I2C interface. Note the I2C address must be set before the evaluation board software is launched. When inserted, the address bit is set to 0. When removed, the address bit is set to 1. This link chooses the second LSB bit of the chip address on the USB I2C interface. Note the I2C must be set before the evaluation board software is launched. When inserted, the address bit is set to 0. When removed, the address bit is set to 1. This link chooses the third LSB bit of the chip address on the USB I2C interface. Note the I2C address must be set before the evaluation board software is launched. When inserted, the address bit is set to 0. When removed, the address bit is set to 1. This link selects whether the supply at VSS is sourced from ground or from AVSS the input. If sourced from ground, the evaluation board becomes a single supply system. Position A: VSS sourced from AVSS. Position B: VSS is connected to ground. This implies single-supply operation of the ADG2188. This link selects whether the logic supply power comes from the USB power (if connected to a PC) or from the user supplied VL (if used as a standalone unit). When inserted, logic power supply comes from USB supply power, that is, 3.3 V. When removed, logic power supply comes from the user supplied VL. Rev.

The default link options are listed in Table 2. The EVAL-ADG2188EBZ can also be used as a standalone board. This option is designed for a PC without a USB port or for users to use the I2C interface within the system being evaluated. Table 3 lists the link options that must be set to operate the evaluation board without a PC. Table 2. Default Link Options Link No. LK1 LK2 LK3 LK4 LK5 Option Inserted; therefore, the LSB is 0. Inserted; therefore, the second LSB is 0. Inserted; therefore, the third LSB is 0. Position A; therefore, the AVSS input supplies the power to the VSS pin. Inserted; therefore, logic power supply comes from USB power. Table 3. Link Options Setup for Control Without a PC Link No. LK1, LK2, LK3 LK4 LK5 Option User configurable. Does not affect whether the board is connected to a PC or not. Position A. Removed. SMB connectors are provided for the SDA and SCL inputs. Switches turn on and off via the I2C bus. The read/write procedures are provided in the ADG2188 data sheet and must be consulted when using this evaluation board in standalone mode. Rev.

Connect the evaluation board to the USB port of the PC, wait for a few seconds, click Rescan and then click Select. The ADG2188 evaluation kit includes self installing EVALADG2188EBZ evaluation software CD. Install the evaluation software before connecting the evaluation board to the USB port of the PC, ensuring the evaluation board is correctly recognized when connected to the PC. SOFTWARE INSTALLATION 1. Insert the evaluation software CD into the PC. The installation software launches automatically. If it does not, use Windows Explorer to locate the file setup.exe on the CD. Double-click the setup.exe file to begin the installation procedure. 2. At the software installation prompt, select a destination directory. By default, the directory is C:\Program Files\ Analog Devices\ADG2188. After the directory is selected, the installation procedure copies the files into the relevant directories on the hard drive. The installation program creates a program group called Analog Devices with a subgroup called ADG2188 in the Start menu of the taskbar. 3. After the installation of the evaluation software is complete, a welcome window displays for the installation of the ADI PAD Drivers. Click Install to install the drivers. 4. After installing the drivers, power up the ADG2188 evaluation board as described in the Power Supplies section and connect the board to the USB port of the PC using the supplied cable. 05978-103 To install the software, Figure 3. Hardware Select Dialog Box Reinitialize Software Click Reinitialize Software in the Configuration tab to reset the software to the default state. Reinitialize the software whenever the evaluation board is reconnected to the PC or if a new evaluation board isused. Setting the I2C Address The device address is set in the Device Address tab (shown in Figure 4). SOFTWARE OPERATION 05978-104 To launch the software, click Start > All Programs > Analog Devices > ADG2188 > ADG2188 Evaluation Software. The Configuration tab of the evaluation software displays as shown in Figure 2. 05978-102 Figure 4. Device Address Tab Figure 2. Configuration Tab Set the device address by clicking on the relevant bit. Click Set Device Address to update the device address in the software. Note the address set must correspond to the address set with the jumpers on the evaluation board and must be set before the evaluation board software begins to function. Rev. A | Page 5 of 12 UG-915 EVAL-ADG2188EBZ User Guide LDSW (Load Switch) If the load switch function in the Configuration tab is on, the switches can update simultaneously (for example, for RGB colors in video switching). Otherwise, if the load switch is off, the switch condition updates upon completion of each I2C write, that is, immediately upon clicking an LED button on the Analog Crosspoint Switch Control in the Configuration tab. The LED is green if the switch is on and is black if the switch is off. 05978-105 If the load switch is on, clicking an LED in Analog Crosspoint Switch Control stores the switch status temporarily until Update Switches is clicked. When an LED is clicked, a red LED indicates the switch turns on and a dark green LED indicates that the switch turns off. All switches update simultaneously upon clicking Update Switches. The red LEDs turn green and the dark green LED turns black, indicating the switches are on and off, respectively. Figure 5. Switch Status Tab Switch Status RESET Function To see what the status of the switch array is at any given time, click the Switch Status tab (shown in Figure 5). The green LED in the Analog Crosspoint Switch Status indicates that the switch is on and the black LED indicates the switch is off. There is a RESET button on the board that can reset the switch array. Alternatively, clicking Reset All (Off) in the Configuration tab of the software resets all switches. All On Function Clicking All On button in the Configuration tab of the software turns on all the switches. Rev.
