Table 34 (ADC Performance Specifications for Intel® MAX® 10 Single Supply Devices) in the MAX 10 FPGA Device Datasheet specifies a Vref-minimum of VCC_ONE - 0.5V.
One of our existing designs violates this specification with Vref = 2.5V and VCC_ONE = 3.3V.
What are the risks in this usage? Can this cause failure of the entire part? Can this cause failure of the ADC?
