Software Configurable Analog Input Types:
  - 12-Channel Single-Ended
  - 6-Channel Pseudo-Differential
  - 6-Channel Fully Differential
Internal +2.5V Reference or External: 1V to VDD
Rail to Rail Common Mode Input Range
Low-Power Consumption
  - 15mW max. at 1MSPS with 2.7V supplies
  - 37mW max. at 1MSPS with 5.25V supplies
Dual conversion with read at 20 MHz SCLK
Single-Supply Operation: +2.7V to +5.25V
