Hi Klaus & FvM,
Sorry for not replying earlier, just come back from hols.
Yes I agree with your point FvM about offsetting, I'll consider what level of adjustment after stress testing the design.
Both, you wish I can mark this thread as solved.

Hi Klaus,
Did the necessary digging and found the circuit you were referring to, then cranked the formula for it:
I had used the spare op amp in the MCP602 to provide a voltage reference and these were my results:
I think, other than the slight curve at the lower end of the slope, it is...
Hi Klaus,
Here's what I have so far:
The circuit:
The graph of what I want:
The trendline of the is only accurate for both the blue flat line and slope. The slope itself described by Y=2.5x-6.25. I need the circuit to implement the slope.
At the mometn the circuit output doesn't...
Hello all,
Firstly, thanks for taking the time to reply to my post.

I ideally wanted the ACS715LLCTR-20A-T but availability is beyond samples seems to be difficult.

AOP??
I'll look into the MCP6s22 and see if it will do the job.
No the MCP602 isn't...
Hi Guys,
I need to sense DC current of a 300vdc power rail. The amps to be sensed are in the range of 0-10A.
I currently have a ACS712ELCTR-20A-T hooked up to a PIC and can measure the output no problem. At 0amps I can read 2.5v at the adc and the voltage swings as the current changes, no...
