ELECTRICAL CHARACTERISTICS (continued)
(+3V ≤ V
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 causes
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
Note 6: C
Note 7: Input filters on SDA, SCL, and ADD suppress noise spikes less than 50ns.
