Forum Post: MSP432P401R: Connecting 12 ADS8688's to MSP432 with SPI

Part Number: MSP432P401R Hi, I have this battery system that is wired as 8 parallel columns of 6 series batteries (48 total). With each battery roughly 1.5 V each, each column has 9 V at the top. I am looking to measure the voltages of the batteries, with 2 data points for each battery, so 96 data points total. Now I chose the ADS8688 because my experiments in the past has caused battery polarity reversal to the batteries, which would cause the need for my ADC to have bipolar inputs. I have some questions for you if you can help me with attempting to connect these ADC's to an MSP432 so I can store my data: 1. First, is it possible to connect 12 of these ADC's with SPI? Or do I need to find an ADC with more inputs so I can limit the number of ADC's I need. 2. Now the MSP432 does not take negative inputs. I plan on using this op amp circuit attached to the end of the ADC to adjust the values so everything is positive. Do you know what pin I need to connect the circuit out of? Aka I am unclear what the output pin is. Please let me know if anything is unclear or if you have any questions for me. Thank you in advance for your help
