data sheet DAC8830/DAC8831-EP_revC_APR2007 :
the table 2 page 21 for bipolar code seems wrong for the 4 last lines :
1000 0000 0000 0000 / VREF ´ (1/32,768)
0111 1111 1111 1111 / 0 V
0000 0000 0000 0001 / VREF ´ (1/32,768)
0000 0000 0000 0000 / VREF ´ (32,767/32,768) = –VREF
data sheet DAC8830/ DAC8831_revD_SEP_2007
the table 2 page 19 for bipolar code seems correct for the 4 last lines :
1000 0000 0000 0001 / +VREF ´ (1/32,768)
1000 0000 0000 0000 / 0 V
0111 1111 1111 1111 / VREF ´ (1/32,768)
0000 0000 0000 0000 / VREF ´ (32,768/32,768) = –VREF
Can you update the data sheet ?
Best regards
