TEMPSENSE1 - Temperature Sensor Calibration Register 1
DACAGAINCAL - DACA Gain Calibration Register
DACAOFFCAL - DACA Offset Calibration Register
DACBGAINCAL - DACB Gain Calibration Register
• Bit 7:0 - TEMPSENSE0[7:0] - Temperature Sensor Calibration Byte 0
This byte contains the byte 0 (8 LSB) of the temperature measurement.
• Bit 7:0 - TEMPSENSE1[7:0] - Temperature Sensor Calibration Byte 1
This byte contains byte 1 of the temperature measurement.
• Bit 7:0 - DACAGAINCAL[7:0] - DACA Gain Calibration Byte
This byte contains the gain calibration value for the Digital to Analog Converter A (DACA). Cali-
bration of the Digital to Analog Converters are done during production test of the device. The
calibration byte is not loaded automatically into the DAC Gain Calibration register, and this must
be done from software.
• Bit 7:0 - DACAOFFCAL[7:0] - DACA Offset Calibration Byte
This byte contains the offset calibration value for the Digital to Analog Converter A (DACA). Cal-
ibration of the Digital to Analog Converters are done during production test of the device. The
calibration byte is not loaded automatically into the DAC Offset Calibration register, and this
must be done from software.
