I am using an AD7533 10bit multiplying DAC which can work with either unipolar or Bipolar (offset) binary codes. I have unipolar digital signals that are generated by a 4040N 12-tage binary counter that I input to AD7533 and it works fine in unipolar mode which goes from 0 (LSB) to -Vref (MSB), now I am trying to make it work in bipolar mode so that I can have -Vref(LSB) to +Vref(MSB). For this I need to input bipolar digital signals (-5V - +5V) rather than unipolar (0-5V), rather than using op-amps for each bit, are there any ready to use converters with multiple inputs and outputs available?
thanks
