MAX6625/MAX6626
9-Bit/12-Bit Temperature Sensors with
I2C-Compatible Serial Interface in a SOT23

ELECTRICAL CHARACTERISTICS (continued)
(+3V ≤ VS ≤ +5.5V, TA = -55°C to +125°C, unless otherwise noted.)
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
self-heating and temperature drift; see the 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’s falling edge.
Note 6: CB = total capacitance of one bus line in pF. Tested with CB = 400pF.
Note 7: Input filters on SDA, SCL, and ADD suppress noise spikes less than 50ns.
