ADS7816
The ADS7816s and the DSP56004 can all be placed into a
power down mode. Or, the DSP56004 can run the ADS7816s
at a full 3.2MHz clock rate while on-board software enables
the ADS7816s as needed. With additional glue logic, the
DSP56004 could be used to run multiple DAC56s or provide
CS controls for each of the three ADS7816s.
FIGURE 7. Flexible Data Acquisition System.
Figure 8 shows a basic data acquisition system. The ADS7816
input range is 0V to 5V, as the reference input is connected
directly to the +5V supply. The 5
to 10
resistor and 1
μ
F
to 10
μ
F capacitor filter the microcontroller “noise” on the
supply, as well as any high-frequency noise from the supply
itself. The exact values should be picked such that the filter
provides adequate rejection of the noise.
