ADGS1414D

• SPI with error detection
  • Includes CRC, invalid read and write address, and SCLK count error detection
• Analog supply voltages
  • Dual-supply: ±4.5 V to ±16.5 V
  • Single-supply: 5 V to 20 V
• PC control in conjunction with the evaluation software
• EVAL-SDP-CB1Z (SDP-B) system demonstration platform

The EV-ADGS1414DSDZ is the evaluation board for the ADGS1414D. The ADGS1414D is an iCMOS®, octal SPST switch controlled by a serial peripheral interface (SPI). The SPI has robust error detection features, including cyclic redundancy check (CRC) error detection, invalid read and write address detection, and SCLK count error detection. The ADGS1414D also supports burst mode, which decreases the time between SPI commands.

Figure 1 shows the EV-ADGS1414DSDZ in a typical evaluation setup. The EV-ADGS1414DSDZ is controlled by the system demonstration platform (SDP) EVAL-SDP-CB1Z (SDP-B), which connects to a PC via a USB port. The ADGS1414D is on 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 SDP-B. The EVAL-SDP-CB1Z (SDP-B) controller board is available to order on the Analog Devices, Inc., website.

For full details on the ADGS1414D, see the ADGS1414D data sheet, which must be consulted in conjunction with this user guide when using this evaluation board.

Equipment Needed

• EVAL-SDP-CB1Z (SDP-B) controller board
• DC voltage source
  • ±16.5 V (dual supply)
  • 20 V (single supply)
• Optional 3.3 V digital logic supply
• Analog signal source
• Method to measure voltage, such as a digital multimeter (DMM)

• 24-lead, 4 mm × 4 mm LFCSP evaluation board
• Easily changeable socket for the main device
• Gold pin connectors for the addition of passive components
• SMB connectors for the input and output of signals
• Additional space on board for prototyping

The EVAL-24LFCSPEBZ enables easy evaluation of the 24-lead lead frame chip scale package (LFCSP) devices in the Switches and Multiplexers Portfolio portfolio that are purchased separately. The EVAL-24LFCSPEBZ is supplied with a socket to secure a 24-lead LFCSP device to the evaluation board without the need for soldering. In addition, there are three sets of gold pin connectors in each trace, allowing board flexibility and reusability for multiple evaluations.

Figure 1 shows the EVAL-24LFCSPEBZ. A 24-lead LFCSP device can be inserted into the socket in the center of the evaluation board. Each device pin has a corresponding 3-pin header link, from K1 to K24, that can either be connected to an external signal source by removing the corresponding link or by using the link to choose between VDD or GND. A wire screw terminal, J1, supplies the VDD and GND. The Subminiature Version B (SMB) connectors on the EVAL-24LFCSPEBZ allow additional external signals to be supplied to the device. In addition, there is a perfboard space and two 24-lead LFCSP pads (4 mm × 4 mm) available on top of the EVAL-24LFCSPEBZ for prototyping.

The full specifications of the device under test (DUT) are available in the corresponding product data sheet, which must be consulted with the EVAL-24LFCSPEBZ user guide when using the EVAL-24LFCSPEBZ.
