NE1617A
Temperature monitor for microprocessor systems
 
[1]   Specifications from -40 癈 to +125 癈 are guaranteed by design, not production tested.
[2]   Guaranteed but not 100 % tested.
[3]   Quantization error is not included in specifications for temperature accuracy. For example, if the NE1617A device temperature is exactly
+66.7 癈, the ADC may report +66 癈, +67 癈 or +68 癈 (due to the quantization error plus the -0.5 癈 offset used for rounding up) and
still be within the guaranteed ? 癈 error limits for the +60 癈 to +100 癈 temperature range.
[4]   T
remote
 is the junction temperature of the remote diode. See Section 7.1 
Temperature measurement

 for remote diode forward voltage
requirements.
