ADS126xEVM Hardware
2.3.1.2 Bench Power Supply
To use the MMB0 with an external bench power supply, remove the J12 jumper and leave it open, as
shown in
Figure 7 . Removing the jumper allows an external 5-V power supply to be connected to +5VA on
the J14 terminal block. Jumper J13B co5VA to +5VD and must remain shorted. In this
configuration, the MMB0 derives the 3.3-V digital supply for the ADS126xEVM from the 5-V bench supply,
and the bench supply directly supplies the analog supply voltage for the ADS126xEVM.
