* IN+, IN-: Analog inputs. Transients from sampling caps are simulated. Input range is +/-VREF
* REF: For 5V VREF VDD should be 5.4V +/-100mV
* VDD: For REF=4.096V VDD=4.75V to 5.25V For REF=4.5V VDD= 4.8V to 5.25V
* Digital Out: Digital representation of output. +/-2^23 This can be used to drive DAC inputs
* Vout: Analog output +/-VREF
* CNV: 2MHz max 0V-1.8V logic level
* RSTn: Resets ADC. Tie to 1.8V for normal operation
