2.2 Evaluation Board Feature Identification Summary
Figure 2-3. ADC368xEVM Feature Identification
Ensure that jumper J16 is shunted in the 2-3 position. This allows 5 V to be supplied to the ADC368xEVM
through the mini-USB connector.
If an external 5-V supply is desired, J16 must be shunted in the 1-2 position, and the external 5 V can be
connected to the test point labeled "+5 EXT". The USB data connection will still be connected for SPI
communications.
J13 is tied to the REFBUF pin. It can be left floating, or can be tied to 1.8V (shunt pins 2-3) for normal operation.
J14 is tied to the PDN/SYNC pin. It can be left floating for tied to ground (shunt pins 1-2) for normal operation. To
power down the ADC, tied to 1.8V (shunt pins 2-3). The ADC may also be powered down via SPI.
