MODEL LR-F28335DAQ8x8
Complete Product Information
The Link Research model LR-F28335DAQ8x8 is a piggyback board designed to function with the model LR-F28335DAQ. It increases the number of A/D and D/A channels to a maxumum of 16 each. This board must be used with the model LR-F28335DAQ and the F28335 eZdsp™ development system from Spectrum Digital, Inc™. It cannot be used alone. This board has a 3 conductor pigtail connector, intended to be plugged into the F28335DAQ board. This allows for only one +/- 15V analog power supply to be used for both boards (see images below).
This product is not compatible with the F2812 eZdsp board. Please see our model LR-F2812DAQ8x8 for use with the F2812 eZdsp development system.

This image shows both the model LR-F28335DAQ and the LR-F28335DAQ8x8 daughtercards stacked up and plugged into the F28335 eZdsp board. This configuration results in a maximum of 16 A/D and 16 D/A channels. All 16 A/D channels can be sampled simultaneously, and all 16 D/A channels can be updated simultaneously.
Notice the analog power pigtail on the right. This allows a single ±15V analog power supply to provide power to both daughtercards.

This is an edge view of the above left image. The bottom board is the F28335 eZdsp board. The next board up is the model LR-F28335DAQ8x8, which contains 8 A/D and 8 D/A channels. The top board is the model LR-F28335DAQ, populated with 8 A/D and 8 D/A channels, along with other peripherals like an RS-232 serial port, 2 user LEDs, 8 digital inputs, etc. Notice the increased distance between the eZdsp board and the LR-F28335DAQ8x8 board. This is achieved with a set of extender connectors, which is included with the purchase of the LR-F28335DAQ. The reason these extenders are required is because of the tall DSP socket present on the F28335 eZdsp board.
