When the buffer is OFF, the
minimum resistive load
between DAC_OUT and V
have a 1% accuracy is 1.5 M
Maximum capacitive load at
DAC_OUT pin (when the buffer
is ON).
It gives the maximum output
excursion of the DAC.
It corresponds to 12-bit input
code (0x0E0) to (0xF1C) at
V
(0xEAB) at V
It gives the maximum output
excursion of the DAC.
