[1] Specifications from −40 °C to +125 °C 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 °C, the ADC may report +66 °C, +67 °C or +68 °C (due to the quantization error plus the −0.5 °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.
[4] Tremote is the junction temperature of the remote diode. See Section 7.1 “Remote diode selection” for remote diode forward voltage
requirements.
