Rofs pin of AD5556

Can the Rofs pin of the AD5556 be left unconnected when used in unipolar two-quadrant mode?  It appears that this would increase the feedback resistance from 5kΩ to 10kΩ.  Would this then also increase the output range from 0V - Vref to 0V to 2Vref?

  • Hi Ivan,

    Thank you for responding.

    I'm going to connect the parallel data inputs to the databus of a non-volatile memory and modify the effective reference input to 'compensate' the contents of the NVM.  The effective reference input ended up being -1.5V, so I was hoping to find a way to 'boost' the output to increase the range without adding additional components and decreasing the reliability of the system.

    Thanks,

    James
