LIS2DH12: what is the typical value fof Temperature senor output change vs temperature in high resulution mode.

In the Datasheet for the LIS2DH12, the typical value for Temperature sensor output change vs temperature is specified for 8 bits low resolution as (typ)1 digit/deg C, but there is no reference for the high resolution mode. Can I have the typical value for TSDr when high resolution mode is activated please?

Thanks

hi, according to LIS2DH12 app note: "The temperature is available in OUT_TEMP_L (0Ch), OUT_TEMP_H (0Dh) stored as two’s complement data, left-justified. The temperature data format can be 10 bits if LPen (bit 3) in CTRL_REG1 (20h) is cleared (high-resolution / normal mode), otherwise, in low-power mode, the ADC resolution is 8-bit."

According to the ds the output change vs T is 1digit/°C on 8 bit also for normal mode [bit1to bit10], so the bit8 will change after a 1°C step, while the LSBs bit9 and bit10 will change inside the 1°C step.
