ADS1259EVM-PDK Operation
9.3 Connecting the Power Supply
The ADS1259EVM-PDK can be operated with a combination of +5V and bipolar (±10V to ±15V) supply.
When the MMB0 DSP is powered properly, LED D2 glows green. The green light indicates that the 3.3V
supply for the MMB0 is operating properly. (It does not indicate that the EVM power supplies are
operating properly.)
9.3.1 Using the +6V Wall Supply for +5V
An ac adapter can be connected to barrel jack J2 on the MMB0. J2 is located next to the USB connector.
The adapter must output 6V to 7V dc. The connector must be sleeve-negative, tip-positive. It should have
a current rating of at least 2A.
Jumper J12 on the MMB0 connects a wall-mounted power supply to the board. To use the wall-mount
supply, J12 must be shorted.
Figure 15 illustrates how to connect an ac adapter to the MMB0.
