• 16-lead, 4 mm × 4 mm LFCSP evaluation board
• Easily changeable clamshell 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-16LFCSPEBZ enables easy evaluation of the 16-lead lead frame chip scale package (LFCSP) devices in the Switches and Multiplexers Portfolio that are purchased separately. The EVAL-16LFCSPEBZ is supplied with a clamshell socket to secure a 16-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, for board flexibility and reusability for multiple evaluations.

Figure 1 in the user guide shows the EVAL-16LFCSPEBZ. A 16-lead LFCSP device can be inserted into the socket in the center of the evaluation board. Each device pin has a corresponding three-pin header link, from K1 to K16. This can either be connected to an external signal source by removing the corresponding link or use the link to choose between V_DD or GND. A wire screw terminal, J5, supplies the V_DD and GND. The Subminiature Version B (SMB) connectors on the EVAL-16LFCSPEBZ allow additional external signals to be supplied to the device. In addition, there is a perfboard space and two 16-lead LFCSP pads (3 mm x 3 mm and 2.1 mm x 2.1 mm) available on top of the EVAL-16LFCSPEBZ 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-16LFCSPEBZ user guide when using the EVAL-16LFCSPEBZ.

• PC software for control and data analysis of time and frequency domain

The ADSKPMB10-EV-FMCZ signal chain kit is a two-board solution, which consists of a Precision Medium Bandwidth Data Acquisition Solution on a PMOD form factor and a Fully Isolated PMOD-to-FMC interposer board.

The Precision Medium Bandwidth Data Acquisition Solution features a discrete programmable gain instrumentation amplifier (PGIA) that was built using a 30V, High Speed, Low Noise, Low Bias Current, JFET Operational Amplifier, the ADA4627-1, a Precision Quad Matched Resistor Network, the LT5400, a Low Capacitance, 4-Channel, ±15 V/+12 V iCMOS^™ Multiplexer, the ADG1209 and the internal Fully Differential Amplifier (FDA) ADC driver of the ADAQ4003. The PGIA in thru front-end offers high input impedance that allows direct interface with a variety of sensors. A programmable gain is often needed to adapt the circuit to different input signal amplitudes—unipolar or bipolar and single-ended or differential with varying common-mode voltages. The PGIA works with the ADAQ4003, an 18-Bit, 2 MSPS, µModule^® Data Acquisition Solution.

The Fully Isolated PMOD-to-FMC interposer board was designed using a Low Noise, 1A, 1MHz Push-Pull DC/DC Driver with Duty Cycle Control, the LT3999, a Robust 3.0kVrms Digital Isolators w/ Fail-Safe for the SPI lines and PGIA gain control pins, the ADuM152N and the ADuM120N, and a Low noise and ultra-low noise LDO regulators the ADP7105 and the ADP150N respectively.

APPLICATIONS

• Data acquisition and system monitoring
• Automated test equipment
• Instrumentation 
• Medical equipment

• 16 lead TSSOP evaluation board
• Clamp to allow the main device to be changed easily
• Gold pin connectors to allow the addition of passive components
• SMB connectors for the input/output of signals
• Additional space on board to allow for prototyping

The EVAL-16TSSOPEBZ evaluation board evaluates 16-lead TSSOP devices in the Switches and Multiplexers Portfolio that are purchased separately. A clamp is supplied with the EVAL-16TSSOPEBZ to secure a 16-lead TSSOP device to the evaluation board without the need for soldering, making the board reusable for multiple devices.

A 16-lead TSSOP device can be clamped or soldered to the center of the evaluation board. Each pin of the device has a corresponding link from K1 to K16 that can be set to either VDD or GND. A wire screw terminal supplies VDD and GND. SMB connectors on the board allow additional external signals to be supplied to the device. In addition, there is space available at the top of the board for prototyping.

Full specifications of the device under test (DUT) are available in the corresponding product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
