Note 1:

Accuracy is guaranteed by the following table:

Note 2:

Offset is measured at the code closest to 10mV.

Note 2:

The temperature coefficient is determined by the “box” method, in which the maximum

V

OUT

over the temperature range

is divided by

T and the typical reference voltage.

Note 4:

Accuracy is better than 1.0LSB for V

OUT

= 10mV to (V

DD

- 180mV). Guaranteed by PSR test on end points.

Note 5:
