General Description
This user guide describes the EVAL-AD8460SDZ board,
which evaluates the AD8460 offered in a 12 mm × 12 mm,
80-lead thin quad flat package (TQFP) with an exposed
pad at the top for a mountable heat sink. The evaluation
board provides a platform for quick and easy evaluation of
the AD8460 for various user-defined configurations.
The AD8460 is ideally suited for demanding applications
such as high-speed arbitrary waveform generation,
programmable power supplies, and LCD/OLED panel
formation.
The evaluation board hardware and software enable full
operation of the AD8460 analog pattern generation (APG)
and arbitrary waveform generation (AWG) modes. The
AD8460 data sheet provides the full specifications of the
AD8460 and details on the device operation. Consult it in
conjunction with the user guide.

  • Page 2: Initial Setup

    AD8460 Evaluation Board User Guide Initial Setup The complete AD8460 evaluation system includes the AD8460 evaluation board, SDP board, and the AD8460 ACE plug- in. Plug-ins are product-specific applications downloaded and run in the analysis/control/evaluation (ACE) software environment. The AD8460 evaluation board communicates with Microsoft Windows 10 and ACE software through the SDP board.
  • Page 3 AD8460 Evaluation Board User Guide Evaluation Board Software Installation 1. Download the ACE installer software from www.analog.com/ace. 2. Install the ACE application and any other recommendations like SDP drivers. Note: This might require a system reboot at the end. So, save any open files and close any other running applications beforehand.

  • Page 5 AD8460 Evaluation Board User Guide Mount the heat sink and secure four screws (PN 9902) onto the board with four hex nuts (PN HNSS440), as shown in Figure 7. Use a torque screwdriver to alternatively tighten the four screws, alternating diagonally like tightening lug nuts on a car tire, to 6 in-oz on each.
  • Page 6 AD8460 Evaluation Board User Guide Use four screws (PN 010440CD125) to secure the fan onto the standoffs. Then, attach the black wire of the fan to FAN_GND and attach the red wire of the fan to FAN_VCC of the female connector P11. See Figure FAN CONNECTION Figure 9.
  • Page 7 AD8460 Evaluation Board User Guide A load capacitor can be installed on the board at C8, or an off-board load may be connected through the OUT_RES test point. Use caution when driving a load that the AD8460 does not exceed its maximum allowable temperature of 150°C. Connect the high voltage supply through VEE_HV, VCC_HV, and GND test points.

    Consult the evaluation board user guide prior to connecting any load to the evaluation board output. If there is unceramictainty as to the load specification, contact an Analog Devices representative. During normal operation, some circuit components may generate significant heat, which may cause fire, melting, or burns. When placing measurement probes near these devices during normal operation, be aware that these devices may be hot.
