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 7 Turn off the supplies. Mate the SDP-H1 board to the AD8460 board through P6, the 120- pin connector at the bottom side of the AD8460 board, if using APG mode only. For a more secure connection, screw the boards together through the connectors’ mounting holes.
  • Page 8 High Z. Run the ACE application. The AD8460 Board plugin for P6-connected board or the AD8460 FMC Eval Board plugin for P- 7 connected board appears in the attached hardware section of the Start tab. Refer to item 1 in the Known Issues section if the board does not appear under the attached hardware section.
  • Page 9 Figure 16. Successful Connection Indicator for FMC Connected Board The AD8460 main functions are labeled in the Block Diagram View or Chip View. This view can be accessed by double- clicking the AD8460 symbol in the board view. This view provides a basic representation of the board’s functionality.

    This button and LED indicator light up green in normal operation and red when the part goes into shutdown. Shutdown Reset After a shutdown event due to a fault condition, reset the shutdown feature to turn the AD8460 back on. This button resets the shutdown feature by writing a 1 and then a 0 to bit[7] of 0x00.

When SDN_IO is pulled high, the AD8460’s supply current is reduced to ~100 µA and the internal high voltage driver is disabled. The S4 switch button toggles the SDN_RESET pin on the AD8460 high. This is an alternative way of exiting a state of shutdown.

    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.
