EVALADBMS1818 - VREG 3.3V or 5V

Thread Summary

The user measured 3.2V on the VREG pin of EVAL-ADBMS1818 while using DC2026 Linduino One in SPI mode, but the datasheet specifies 5V. The final answer confirms that VREG should be supplied with 5V for proper AFE operation.

Hello,

I'm doing some test on EVAL-ADBMS1818 with DC2026 Linduino one. The setup is in SPI mode. During the test, i measured the VREG pin and it is 3.2V. The datasheet stated that is should be 5V. As i'm going to design a board and use an external supply of 5V to VREG. I would like to check whether I should supply 5V or 3.3V to this pin.

Thank you.
