Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect

Note 1:
All devices 100% production tested at T
A
= +85°C. Limits over temperature are guaranteed by design.
Note 2:
Guaranteed but not 100% tested.
Note 3:
Quantization error is not included in specifications for temperature accuracy. For example, if the MAX1617A device tempera-
ture is exactly +66.7°C, the ADC may report +66°C, +67°C, or +68°C (due to the quantization error plus the +1/2°C offset used
for rounding up) and still be within the guaranteed ±1°C error limits for the +60°C to +100°C temperature range (Table
2).
Note 4:
A remote diode is any diode-connected transistor from
Table 1.
T
R
is the junction temperature of the remote diode. See
Remote-Diode Selection
for remote diode forward voltage requirements.
Note 5:
The SMBus logic block is a static design that works with clock frequencies down to DC. While slow operation is possible, it
violates the 10kHz minimum clock frequency and SMBus specifications, and may monopolize the bus.
Note 6:
Note that a transition must internally provide at least a hold time in order to bridge the undefined region (300ns max) of
