1.5. Intel® MAX® 10 ADC Conversion
The ADC in dual supply Intel® MAX® 10 devices can measure from 0 V to 2.5 V. In single supply Intel® MAX® 10 devices, it can measure up to 3.0 V or 3.3 V, depending on your power supply voltage.
- In prescaler mode, the analog input can measure up to 3.0 V in dual supply Intel® MAX® 10 devices and up to 3.6 V in single supply Intel® MAX® 10 devices.
- The analog input scale has full scale code from 000h to FFFh. However, the measurement can only display up to full scale – 1 LSB.
- For the 12 bits corresponding value calculation, use unipolar straight binary coding scheme.

The Intel® MAX® 10 ADC is a 1 MHz successive approximation register (SAR) ADC. If you set up the PLL and Modular ADC Core IP core correctly, the ADC operates at up to 1 MHz during normal sampling and 50 kHz during temperature sensing.
Note: The analog value represented by the all-ones code is not full scale but full scale – 1 LSB. This is a common convention in data conversion notation and applies to ADCs.
