ADG1408L

• Single inline headers provide flexibility for the field programmable gate array (FPGA) or microcontroller 1.2 V or 1.8 V logic input signals
• Surface-mount device (SMD) pin resistor or capacitor sockets available for the addition of passive components
• SMB connector sockets provide flexibility for the input and output signals

The EVAL-ADG1408LEBZ is the evaluation board for the ADG1408L. The ADG1408L contains an eight channel multiplexer. The ADG1408L switches one of eight inputs to a common output, as determined by the 3-bit binary address lines, A0, A1, and A2. The enable pin (EN) is used to enable or disable the device. When disabled, all channels are switched off. When enabled, each channel conducts equally well in both directions and has an input signal range that extends to the supplies.

An external V_L supply pin provides logic control flexibility for lower logic controls. The ADG1408L is both 1.2 V and 1.8 V JEDEC standard compliant.

Figure 1 in the user guide shows the EVAL-ADG1408LEBZ in a typical evaluation setup. The EVAL-ADG1408LEBZ is located in the center of the evaluation board, and wire screw terminals are provided to connect each source and drain pin. Three screw terminals are used to power the device, and an external pin provides users with a defined digital logic supply voltage. Alternatively, the digital logic supply voltage can be supplied from a 5-pin header.

Full specifications on the ADG1408L are available in the ADG1408L data sheet available from Analog Devices, Inc., and must be consulted in conjunction with the user guide when using the EVAL-ADG1408LEBZ.

• 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.
