NOTES:
1. The following formula can be used to calculate the temperature sensor output voltage:
VSensor, typ = TCSensor ( 273 + T [°C] ) + VOffset, sensor [mV]
2. Results based on characterization and/or production test, not TCSensor or VOffset, sensor.
Measured with fSD16 = 1MHz, SD16OSRx = 256, SD16REFON = 1.
