@crutschow Great thanks,
Please check if my wiring is correct.



Also, I will appreciate a lot if you could explain in brief how you calculated the resistances (considering gain)..

 

Okay, I didn't notice that it has a differential output.
Do you know what the common-mode voltage output is (DC bias voltage common to both outputs). It wasn't listed in the data sheet.
That will determine what type of circuit you need.

 

@crutschow I have one more document which is the application note.. maybe this would help.

 

That's not a single-supply device.

Uh Oh, no it isn't it does require a dual supply +/-.

 

I don't have experience with amps, so I would ask if I can use dual supply amp with 5V and 3.3V?

 

@crutschow I have one more document which is the application note.. maybe this would help.

That doesn't give the info either.
Since we don't know that voltage, an Instrumentation Amp with a differential input as Reloadron suggested would likely be better.
Here's a single supply, rail-rail one that should work for you (data sheet here).
(A dual supply means it requires both plus and minus supply voltages).

For a gain of 50 use a 1.02kΩ resistor for Rg, connected between pins 1 and 8.
Connect pins 4 and 5 to ground and +5V to pin 7.
Note that its maximum supply voltage is 7.5V.

 

@crutschow is this correct?

Yes.

I will try to download the Spice model for that and run a simulation to make sure there's no obvious problems with using that device.

 

As I was concerned, those rail-rail instrumentation amps have significant limits on their output voltage, depending upon their input voltage and will output the maximum voltage (5V) only if the input is biased at 1/2 the supply voltage (2.5V).

Thus we really need to know what the output DC bias voltage is from that sensor.

Can you contact the manufacturer and see if they have the info? I'm surprised it's not in their data sheets.

 

@crutschow Hi Wally, I sent them an email asking for the output DC bias voltage.
I will update you as soon as I get an answer.

Thanks a lot for helping.
