I have 2 ADS1299 analog to digital converters(<https://datasheet.octopart.com/ADS1299IPAG-Texas-Instruments-datasheet-17020782.pdf>). I need to give them bipolar mode supplying but I must use a powerbank of 5V 3A. I wonder how can I create a bipolar supply of +2.5v -2.5v as mention in the datasheet from the 5V of the powerbank. I am new in this field. Thank you
