Product Details

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.

The ADT7311 is guaranteed to operate over supply voltages from 2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typically 210 μA. The ADT7311 has a shutdown mode that powers down the device and offers a shutdown current of typically 2 μA. The ADT7311 is rated for operation over the −40°C to +150°C temperature range.

The CT pin is an open-drain output that becomes active when the temperature exceeds a programmable critical temperature limit. The default critical temperature limit is 147°C. The INT pin is also an open-drain output that becomes active when the temperature exceeds a programmable limit. The INT and CT pins can operate in either comparator or interrupt mode.

PRODUCT HIGHLIGHTS

  1. Ease of use, no calibration or correction required by the user.
  2. Low power consumption.
  3. Excellent long-term stability and reliability.
  4. Packaged in an 8-lead SOIC, RoHS-compliant package.
