Hi,
I read in earlier E2E post that it is recommended to center the signal to 2.5V and swing of max +/- 2.5V when TLC5540IPW is used in (0-5V) ref voltage configuration. We are planning to use this ADC with 0-5V configuration so that we get a 5V analog input span but we are not clear what is the necessity to have a centered signal at 2.5V? Could you please clarify more details as to why it is required or any signal between 0-5V when fed as input to ADC shall be converted to 8 bit digital in this configuration.
Please find below the link of earlier post which I am referring to for your reference.
