guys my analogue electronics is weak.. pls bear up
i want to use an ADC to measure voltages in the range of 0.55 volts down to 0.044 volts with respect to ground. im using atmega128 and was wondering could i use this microcontroller directly to digitse the values without using any amplifiers
I understand that i can apply a gain of 20db(2x) for differential inputs and no gain for single ended inputs
SO can i do an adc with a single ended input treating it as a differential(one end to the input and the othe end to ground)?
