Part Number: DAC80502 Tool/software: Dear Technical Support Team, I'd like to confirm DAC ouptut(Vout) with midscale ( RSTSEL = VDD) . According to the datasheet, Vout is defined by the following formula and default settings are DIV=1 and GAIN=2, internal refefence=2.5V. I believe that this default settings means 5V fulll scale with internal reference. Q1: The default setting with midscale code(=8000h), what timing does Vout show 2.5V? For example, VDD POR circuit is following, Vout shows 2.5V after green zone? Q2: When using external reference, I need to change from internal ref=2.5V to external ref=5V and REFDIV=1 (reference divided by 2) and GAIN=1 (gain at both the DAC outputs is 2) following steps. At this time, will Q1's midcode (Vout=2.5V) be maintained until write new DAC code? Best Regards, ttd
