1 To guarantee a successful readback operation over the full operating temperature range, DVCC must be restricted to within a range of 2.7 V to 3.63 V.

2 Guaranteed by design and characterization; not production tested.

3 Includes noise contributions from integrated reference buffers,16-bit DAC, and output amplifier.
