Hello Ti Team,
I am working with the ADS8671 ADC and I couldn't find anything on how the data should be interpreted or what is needed to set up the ADC.
So I have two questions.
1. If I do not write anything to the ADC and just pull CS low, wait t_conv_max, hold SDI low for 32 Clocks on SPI, (basically sending NOP) will I receive a valid read from the ADC? If not what is required for me to get a valid read? Do any commands need to be written in order for me to get a valid read?
2. If I send a NOP and read the most recent conversion from ADC, how are these 14 bits to be interpreted? I couldn't find this anywhere in the data sheet. Is it signed or unsigned?
For example if I do not set up the ADC, the range should be +-12.288V. What will be the value when the ADC's input Voltage is at 0V, +12V and -12V. Is it 0b00000000000000 for -12.288V and 0b11111111111111 for +12.288V and 0b10000000000000 for 0V?
