Purpose Of Reference Voltage In Adc
Purpose Of Reference Voltage In Adc . During an adc conversion the value of unknown voltage is found by comparing it with a known voltage, this is known voltage is called as reference voltage. The value used as the top of the input range). Can You Use the Voltage Reference to Power Your ADC Driver from www.analog.com Per design the adc reference voltage is 1100 mv, however the true reference voltage can range from 1000 mv to 1200 mv amongst different esp32s. The lm35 outputs 10mv/degc, which at my setup yields 2mv/step or 5steps/degc. For example the pic12f1840 reference voltage can be set to 4.096, 2.048 or 1.024 volts.
