ADS1x7xEVM-PDK Operation
To prepare to evaluate the ADS1278 with the ADS1x7xEVM-PDK, complete the following steps:
1. Verify the jumpers on the ADS1x7xEVM are as shown in
Figure 1
(note that these settings are the
factory-configured settings for the EVM).
2. Using
ADCPro HW/SW Installation Manual
, verify the MMB0 jumpers are in the default position and
install ADCPro and ADS1278EVM plug-in software. Complete hardware connection and driver
installation as part of
ADCPro HW/SW Installation Manual
using the below settings.

Open
•
MMB0 J13B
→
Short
•
No additional power connections are required
3. Plug the ADS1278EVM onto the MMB0 (if not already connected). The female portion of J3, J4 and J5
on the EVM align with male connectors J10, J4, and J5 respectively on the MMB0.
4. Connect power to the MMB0 board. If power is supplied from an AC adapter (not included), ensure that
it satisfies the following requirements:
•
Output voltage: 5.5 VDC to 15 VDC
•
Maximum output current:
≥
500 mA
•
Output connector: barrel plug (positive center), 2.5-mm I.D. x 5.5-mm O.D. (9-mm insertion depth)
•
Complies with applicable regional safety standards
CAUTION
Do not misalign the pins when plugging the ADS1278EVM into the MMB0.
Check the pin alignment of J3, J4, and J5 carefully before applying power to
the PDK.
