Features and Benefits

  • SPI interface with error detection 
  • Includes CRC, invalid read/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 system demonstration platform (SDP) 

Product Details

The EVAL-ADGS1412SDZ is the evaluation board for the ADGS1412. The ADGS1412 is an iCMOS, quad single-pole, single-throw (SPST) switch controlled by a serial peripheral interface (SPI). The SPI has robust error detection features. These are cyclic redundancy check (CRC) error detection, invalid read/write address detection and serial clock (SCLK) count error detection. It is possible to daisy-chain multiple ADGS1412 devices together. This enables the configuration of multiple devices with a minimal amount of digital lines. The ADGS1412 also supports burst mode that decreases the time between SPI commands.


The EVAL-ADGS1412SDZ is controlled by the SDP which connects to a PC via USB. The ADGS1412 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 defined digital logic supply voltage, if required. Alternatively, the digital logic supply voltage can be supplied from the SDP.


Full specifications on the ADGS1412 are available in the ADGS1412 data sheet available from Analog Devices and should be consulted in conjunction with user guide UG-1067 when using the evaluation board.


The evaluation board interfaces to the USB port of a PC via the SDP board. The EVAL-SDP-CB1Z board (SDP-B controller board) is available to order on the Analog Devices website at www.analog.com.

EVAL-24LFCSPEBZ

Evaluation Board for the 24-Lead LFCSP Devices in the Switches and Multiplexers Portfolio

Buy Now View Details

Features and Benefits

  • 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

Product Details

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.
