Yet, I’m only able to gain 8-bit values from the AD-converter. Reviewing the datasheet it seems that the AD7999 is the 8-bit variant out of a serie of AD-converters, and the 10 and 12 bit AD-converters are different SOTs (AD7995 and AD7991 respectively).
Is my intepretation of the datasheet correct, or am I missing a configuration option?
I specifically orderd this item because it provided a 4 channel 12-bit resolution. The answer is therefore a bit dissappointing. Especially, because shipping and taxes tripled its price….
I’m happy to read you modified the description to prevent other people from being misled. I would recommend to provide a 12-bit ADC as standerd option. Even Arduino provides a 10-bit ADC, gaining two extra bits is a plus loosing two seems like a loss.
