APPLICATIONS INFORMATION

INTERFACING THE ADS1605 TO THE

TMS320C6000

Figure 28 illustrates how to directly connect the

ADS1605 to the TMS320C6000 DSP. The processor

controls reading using output ARE. The ADS1605 is se-

lected using the DSP control output, CE2. The

ADS1605 16-bit data output bus is directly connected

to the TMS320C6000 data bus. The data ready output

from the ADS1605, DRDY, drives interrupt EXT_INT7

on the TMS320C6000.

INTERFACING THE ADS1606 TO THE

TMS320C6000

Figure 29 illustrates how to directly connect the

ADS1606 to the TMS320C6000 DSP. The processor

controls reading using output ARE. The ADS1606 is

permanently selected by grounding the CS pin. The

ADS1606 16-bit data output bus is directly connected

to the TMS320C6000 data bus. The data ready output

from the ADS1606, DRDY, drives interrupt EXT_INT7

on the TMS320C6000.
