    resistor mismatch and the resolution

    For a 10bit resistor string DAC, if the INL is required to be less than 1LSB. Why the resistor mismatch delta(R)/R< 1/(2^9)? Why not delta(R)/R< 1/(2^10)?

    Thank you.

    Re: resistor mismatch and the resolution

    Weight of highest bit = 512
    Weight of lowest bit = 1

    Error in highest bit that corresponds to the weight of the lowest bit = 1/512 = 1/(2^9)
