Bits 31:24 – TEMP_TL [7:0]
Bits 19:16 – TEMP_TL [11:8] Temperature TL
The following rule applies to recover the real values of ADC_TEMP_OUT from the 12-bit coded values in the product registers:
ADC_TEMP_OUT[23:0] (TL) = TEMP_TL[11:0] << 12
Note: TEMP_TL[11:0] is a signed 12-bit integer.
Bits 15:8 – REF_TL [7:0]
Bits 3:0 – REF_TL [11:8] Reference Voltage
Reference Voltage measured at temperature TL
VREF(TL) = 1.120V + REF_TL[11:0] * 25 μV
