The A/D converter is used to convert the analog signals to digital signals. For an 8-bit A/D converter with a conversion speed of 1 ms and an analog input range of 0-5V, if a 3.3V analog signal is inputted, the digital signal output should be:
A: 168
B: 3.3
C: 168.9
D: 3
A: 168
B: 3.3
C: 168.9
D: 3
