PRODUCTION DATA.
In register 0x05, the die temperature sensor can be enabled. The sensor is power controlled independently of global powerdown, so that it and the SPI can be used to monitor the die temperature even when the remainder of the ADC is in sleep mode. Register 0x08 is used to read values which can be mapped to the die temperature. The exact mapping is detailed in the register map. Care should be taken not to exceed a maximum die temperature of 150°C for prolonged periods of time in order to maintain the life of the device.
