"The ADT7311 is a high accuracy digital temperature sensor in a narrow 8-lead SOIC package. It contains a band gap temperature reference and a 16-bit ADC to monitor and digitize the temperature to a 0.0078°C resolution. The ADC resolution, by default, is set to 13 bits (0.0625°C). The ADC resolution is a user programmable mode that can be changed through the serial interface."
Qualified for Automotive Applications
Temperature accuracy:
±0.5°C from −40°C to +105°C (2.7V to 3.6V)
±0.4°C from −40°C to +105°C (3.0V)
No temperature calibration/correction required by user
No linearity correction required
Power saving 1 sample per second (SPS) mode:
700 µW typical at 3.3 V in normal mode
7 µW typical at 3.3 V in shutdown mode
Temperature range: −40°C to +150°C
Voltage range: 2.7 V to 5.5 V
Critical overtemperature interrupt
Overtemperature/undertemperature interrupt
SPI-compatible interface
8-lead narrow SOIC RoHS-compliant package
