Part Number: ADS1235
Hi
I have some additional questions to the thread of the ADS1235 (pin assign at Single-ended-input).
That means to use AIN1..5 as single-ended inputs I have to connect e.g. +2.5V (mid range voltage) on AIN0, why should I not connect GND (AVSS) to AIN0? If I create the +2.5V reference on AIN0 by a resistor divider between AVDD and AVSS, do I have the same issues as I use the internal Vcom as reference?
Converting a ground referenced 0..+5V signal on AIN1 with a +2.5V reference on AIN0 end up in positive/negative converted digital data, right?
Summarized, what is the best and easiest way to use AIN1..5 as ground referenced inputs (0..+5V)?
Best Regards
Oliver
