#20619 - RE: Voltage Dividing, an analog problem: |
According to the data sheets, the lm35 can has a .1ohm output impedance with a 1ma load. So you can safely calculate a resistor divider such that the load never exceeds 1ma. And the imput impedence of the adc is 1megohm, so no problem there. So no buffer needed, in my opinion. |
