MODEL LR-F28335DAQA (and Options)

Complete Product Information  


The Link Research model LR-F28335DAQA is a precision, 14-bit, data acquisition daughtercard designed to operate with the F28335 eZdsp™ development system from Spectrum Digital, Inc™. This product is not compatible with the F2812 eZdsp board. Please see our model LR-F2812DAQA for use with the F2812 eZdsp development system.

The daughtercard contains 4 (optionally 8) A/D channels, and 8 D/A channels. All channels have a full +/- 10V range, and are protected against transient voltage spikes. All A/D channels have the capability of being simultaneously sampled, whereas all the D/A channels can be updated simultaneously.

The daughtercard includes miscellaneous peripherals, like 8 user digital inputs, 2 user red LEDs and an RS-232 port with a maximum baud rate of 921.2 kbps.

The daughtercard also includes our model LR-DAQEXTSET4 height extenders, which are necessary to clear the tall DSP socket present on the F28335 eZdsp board.

Several options are available for the daughtercard including a fiber optic serial port for galvanically isolated serial communications with the DSP, and an Ethernet interface. The board ships with everything shown in "What's in the Box" below.

Model Number Description
LR-F28335DAQA This is the standard board containing 4 14-bit A/D Channels, 8 14-bit D/A channels, an RS-232 serial port, 2 general purpose LEDs, 8 general purpose input lines and includes everything shown in "What's in the Box" above.
LR-F28335DAQ-1 This is an option for the model LR-F28335DAQA which adds 4 additional 14-bit A/D channels. With this option installed, the board is capable of simultaneously sampling all 8 A/D channels. Note: This option must be ordered at the time of purchase of the model LR-F28335DAQA.
LR-F28335DAQ-2 This is an option for the model LR-F28335DAQA which adds a fiber optic serial port. This option results in a board containing both an RS-232 serial port and a fiber optic port. The desired port is selected with a jumper. The RS-232 port and the fiber optic port cannot be used simultaneously. This option must be ordered at the time of purchase of the model LR-F28335DAQA.
LR-F28335DAQ-3 This is an option for the model LR-F28335DAQA which adds Ethernet capability to the board. The board will include a Lantronix, Inc. XPort Device Server. Note: This option must be ordered at the time of purchase of the model LR-F28335DAQA. View typical application

The image above shows a typical use of the model LR-F28335DAQA data acquisition daughtercard (middle). Two of the eight available D/A channels have been programmed to output two +/- 10 Volt sinewaves which are 120 degrees out of phase. On the right is a PC running TI's Code Composer Studio (CCS). Notice the DB-9 cable plugged into the left side of the daughtercard. The other end of this cable is plugged into the PC, where HyperTerminal can be run simultaneously with CCS to monitor or control the F28335 eZdsp.

The above image shows the model LR-F28335DAQA daughtercard plugged into the F28335 eZdsp board. This particular daughtercard includes the Ethernet interface option (LR-F28335DAQ-3), as seen on the left side. The configuration shown also includes the LR-F28335DAQ-1 option, which adds 4 additional A/D channels, bringing the total number of A/D channels to 8.

This is an edge view of the above left image. The bottom board is the F28335 eZdsp board.  The top board is the model LR-F28335DAQA, 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.
