EVM Overview
A specific adapter interface card is also available for most of TI’s DSP Starter
Kits (DSK). The card model depends on the type of TI DSP Starter Kit to be
used. When ordering an adapter interface card, specify the DSP that will be
used.
In addition, an MSP430-based platform (HPA449) that uses the MSP430F449
microprocessor can be used with this EVM. For more information regarding
the adapter interface card or the HPA449 platform, please call Texas
Instruments Inc. or email us at [e-mail].
The DAC outputs can be monitored through selected pins of J4. The outputs
of U1 can be switched using their respective jumpers W2, W11, W12, and
W13, for stacking, while U4 or U8 uses only W2. Stacking allows a total of eight
DAC channels (if two DACx574 EVMs are stacked) or two DAC channels (if
two DACx571 EVM are stacked) to be used provided that the I
2
C address is
unique for each stacked EVM board.
Any DAC output can be connected to the noninverting input of op-amp U2 by
using a jumper across the appropriate pins of J4 (See EVM schematic
diagram). U2 must be configured correctly for the desired waveform
characteristic. (Refer to Chapter 3 of this user’s guide.)
A block diagram of the EVM is shown in Figure 1-1.
