    Hello,

    In my project I have to measure the weight of food, using a load cell,instrument amplifier and obviously an A/D converter(the data output goes to the micro controller).

    The load cell I'm using is CZL605D and my excitation voltage is 5V, so the manufacturer said the output will be 1mv/V.

    My problem is how to connect my amplifier.I'm using Analog Devices AD620ANZ amplifier and I do not know how to connect it to the load cell.
    Also I do not know what is the gain required so the signal can be processed by ADC0803 converter.
    The supply for the AD620ANZ is +-5V.

    Thank you.
