with buffer OFF

When the buffer is OFF, the

Minimum resistive load

between DAC_OUT and VSS

to have a 1% accuracy is

1.5 M

CLOAD(2) Capacitive load

Maximum capacitive load at

DAC_OUT pin (when the

buffer is ON).

DAC_OUT

min(2)

Lower DAC_OUT

voltage with buffer

-0.2

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 (0x1C7)

to (0xE38) at VREF+ = 1.7 V
