Digital Interface
The ADS8371EVM is designed for easy interfacing to multiple platforms.
Samtec part numbers SSW−110−22−F−D−VS−K and TSM−110−01−T−DV−P
provide a convenient dual-row-header/socket combination at P2 and P3.
Consult Samtec at www.samtec.com or 1−800−SAMTEC−9 for a variety of
mating connector options.

P2.19 INTc Set jumper W4 to select BUSY or inverted signal
to be applied to this pin.
Note: All even-numbered pins of P2 are tied to DGND.
Read (RD) and conversion start (CONVST) signals to the converter can be
assigned to two different addresses in memory via jumper settings. This allows
for the stacking of up to two ADS8371EVMs into processor memory. See
Table 3−2 for jumper settings. Note, the evaluation module does not allow the
chip select (CS) line of the converter to be assigned to different memory
locations. It is therefore suggested that the CS line be grounded or wired to an
appropriate signal of the processor.
