When the buffer is OFF, the Minimum
resistive load between DAC_OUT
and V
1.5 MΩ
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
and (0x155) and (0xEAB) at V
2.4 V
It gives the maximum output
excursion of the DAC.
With no load, middle code (0x800) on
the input
With no load, worst code (0xF1C) on
