How to measure current? (ADC08034 interface to the AT89C52)

what do you call this connection ? ( i have marked ) high side or low side sensing ?

I think it's "Other side sensing"

To be fair it looks like a valid method,
although the voltages marked are wrong.

Your sense voltage should be more like 0.5 volts
and the opposite polarity( I think ).

>but i cannot get the output in AC form.
Why do you want AC ?, it's a DC circuit, expect DC output

Why are you using 50 Volts ?
such a high voltage is likely to cause problems.

hi christie,
ur ciruit looks perfectly o.k. except for the voltage levels ( just like experimenterUK said) and the output voltage u get would be of -ve polarity. Now this is not recommended as the op-amp is operating on a single +ve supply so u may possibly not get a valid -ve output on pin 6 of the op-amp. So i strongly suggest u interchange the Vin+ and Vin- inputs of the op-amp and generate a +ve DC signal at the output.

I think it's "Other side sensing"

i used High side sensing and Low side sensing but "other side sensing" is new to me, LOL
