The ADT7410TRZ-REEL is a high accuracy digital temperature sensor in anarrow SOIC package. It contains a band gap temperature referenceand a 13-bit ADC to monitor and digitize the temperature to a0.0625°C resolution. The ADC resolution, by default, is set to13 bits (0.0625°C). This can be changed to 16 bits (0.0078°C) bysetting Bit 7 in the configuration register (Register Address 0x03).
The ADT7410TRZ-REEL is guaranteed to operate over supply voltages from2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typically210 μA. The ADT7410TRZ-REEL has a shutdown mode that powersdown the device and offers a shutdown current of typically 2 μA.The ADT7410TRZ-REEL is rated for operation over the −55°C to +150°Ctemperature range.
Pin A0 and Pin A1 are available for address selection, giving theADT7410TRZ-REEL four possible I2C addresses. The CT pin is an open-drainoutput that becomes active when the temperature exceedsa programmable critical temperature limit. The default criticaltemperature limit is 147°C. The INT pin is also an open-drainoutput that becomes active when the temperature exceeds aprogrammable limit. The INT and CT pins can operate in eithercomparator or interrupt mode.
