In AMC7832 ,the ADC can take input voltages in the range -12.5V to 12.5V and it will convert this i/p voltage to digital by taking 2.5V reference .But the issue is how it will convert voltage in the range from -12.5V to 12.5V to 12 bit output?I want to know the conversion of voltage from -12.5V to 12.5V to 12 bit bianary form.
