filename = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/791754/Log_file.txt';
data = readmatrix(filename, 'Range', 'C:C')
data = 10×1
1562 2027 363 2808 2770 5947 3477 340 1131 2775

Your data file looks like a configuration file with key/value pair separated by ':'. One way to parse the data is to do this for each row:
rowStr = 'ADC0/F1 : 1562';
tokens = split(rowStr, ':');
intValue = str2double(strtrim(tokens(2)));
