We use LM358 to do comparator application (V+ 5VSB and V- GND). Currently, the measured result on pin7 is 3.72V. As we can see from datasheet, it define the minimum voltage range of Voh is Vcc-1.5V, ...

Old hands will no doubt guess where this design is heading, there is an LM35 temperature sensor producing a voltage proportional to its temperature, and half of an LM358 which forms a comparator ...
