If you thought the 16Bit ADC1115 is impressive, play with this one. Amazing resolution with 24Bits in little more than 1.3"x2.25" PCB. It took a while to get the software driver configured and get familiar with the ADC1256 internal registers. But, once the ADC is up and running, the performance of this little board is impressive. I am using two differential channels, input signal of +/- 5 millivolt, and 24X gain.
