SBAS740B October 2015 – May 2020 ADS1118-Q1
PRODUCTION DATA.
The ADS1118-Q1 offers an integrated precision temperature sensor. To enable the temperature sensor mode, set bit TS_MODE = 1 in the Config register. Temperature data are represented as a 14-bit result that is left-justified within the 16-bit conversion result. Data are output starting with the most significant byte (MSB). When reading the two data bytes, the first 14 bits are used to indicate the temperature measurement result. One 14-bit LSB equals 0.03125°C. Negative numbers are represented in binary twos complement format, as shown in Table 4.
