Re: How to determine divider resistor as inout to ADC
TLC5540INS (8bit 40MSPS parallel) is the number of my ic. I used this ic for my digital oscilloscope project, so the input would be use a funtion generator to privided ac signal. Another thing is i was tested it by just simply supply a dc voltage, my maximum input range is 2.6, and supposed to obtai...

Re: How to determine divider resistor as inout to ADC
Hi... MrAl
The circuit that you mentioned above is it suitable fot the input of the ADC? because my lecturer said if the circuit will produce current, then cannot use? Can u give some comment, may be you more pro. then my lecturer ..

Re: How to determine divider resistor as inout to ADC
That means the Vref 2.6v is fixed? Let said in the series of resistor, one side fixed with Vref 2.6v and another side use to input signals? Must i put the resistor value to be 100k? If not, how exactly the value of resistor to be determine? My ADC is 8bit, single channel, Vref=2.6v, and operation su...

How to determine divider resistor as inout to ADC
I going to do a digital oscilloscope project. But my ADC is only -0.6v to +2.6V analog input range. I need a voltage id from negative voltage to positive voltage. In my case suppose to get
-2.6v to +2.6. How to the divider resistor? what should be the resistor value? My ref is 2.6v.
