the lm35 with a negative voltage
hi
i am working on a microcontroller 89c51
i want to interface an LM35 to the microcontroller using an ADC
the temp range of the temp sensor is -55C to 150C(-550mV to 1.5V) with a scaling factor of 10mV/C.
the analog input to the ADC is 0-5V
my question is how are the negative voltage values converted on the ADC?
plz help ....its urgent
