STTS751 register summary

STTS751

18/36

Doc ID 16483 Rev 5

Tres1:Tres0 [bits 3 and 2]

These bits select one of the four programmable resolutions for temperature data on the

STTS751 providing resolutions down to 0.0625 °C/LSB. The default resolution is 10 bits,

0.25 °C/LSB.

RFU [bits 1 and 0] Not used - reserved.

Conversion rate register

The STTS751 conversion rate register is read/write and controls the number of times the

temperature value will be updated each second.

The upper four bits of the register are reserved and default to 0 on power-up. The lower four

bits control the conversion rate as shown in the table below. The power-up default is 1

conversion per second. The current draw is proportional to the conversion rate, and goes up

at higher rates.
