Control Register
Threshold Reference for Internal Analog Comparator
ADC Control and Status Register B– ADCSRB
An external resistor used in conjunction with the Current Source can be used as threshold ref-
erence for internal Analog Comparator
connected to AIN0 (negative Analog Compare input pin) as well as AIN1 (positive Analog
Compare input pin). Using a resistor in serie with a lower tolerance than the Current Source
accuracy ( 2%) is recommended.
