When the buffer is OFF, the
minimum resistive load
between DAC_OUT and VSS to
have a 1% accuracy is 1.5 M
CLOAD

Maximum capacitive load at
DAC_OUT pin (when the buffer
is ON).

Lower DAC_OUT voltage with
buffer ON
0.2
V
It gives the maximum output
excursion of the DAC.
It corresponds to 12-bit input
code (0x0E0) to (0xF1C) at
VREF+ = 3.6 V and (0x155) and
(0xEAB) at VREF+ = 2.4 V.

It gives the maximum output
excursion of the DAC.
DAC_OUT
