Note 2:
Guaranteed by design and characterization to ±5 sigma.
Note 3:
Quantization error not included in specifications for temperature accuracy.
Note 4:
Output current should be minimized for best temperature accuracy. Power dissipation within the MAX6625/MAX6626 will
cause self-heating and temperature drift; see
Thermal Considerations
section.
Note 5:
A master device must provide a hold time of at least 300ns for the SDA signal in order to bridge the undefined region of
SCL

Note 7:
Input filters on SDA, SCL, and ADD suppress noise spikes less than 50ns.
