The ADT7410 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 ADT7410 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 ADT7410 has a shutdown mode that powersdown the device and offers a shutdown current of typically 2 μA.The ADT7410 is rated for operation over the −55°C to +150°Ctemperature range.Pin A0 and Pin A1 are available for address selection, giving theADT7410 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.Applications Medical equipment Environmental control systems Computer thermal monitoring Thermal protection Industrial process control Power system monitors Hand-held applications
