DAC80501: DAC80501MDQFT Output Range

Eli Hait54
Intellectual 360 points

Part Number: DAC80501

Hi,

If the VDD=5V and using internal Vref with REF-DIV=0 and BUFF-GAIN=1, what will the maximum VOUT range (it will be less than VDD, right?)?

 

Thanx,
Eli.

    Hi Eli,

    When using those settings, the nominal output will be 5V.  It will be limited by gain error, full-scale error, and supply clipping.  When sourcing current, the DAC also requires more headroom, so your load might impact the full-scale error as well.  Generally, if you need to drive a load and still achieve 5V output, then I recommend you increase your supply voltage (e.g. 5.5V).

    Thanks,

    Paul
