The ADT7420 is a high accuracy digital temperature sensoroffering breakthrough performance over a wide industrialrange, housed in a 4 mm × 4 mm LFCSP package. It contains aninternal band gap reference, a temperature sensor, and a 16-bitADC to monitor and digitize the temperature to 0.0078°Cresolution. The ADC resolution, by default, is set to 13 bits(0.0625°C). The ADC resolution is a user programmable modethat can be changed through the serial interface.The ADT7420 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 ADT7420 has a shutdown mode that powersdown the device and offers a shutdown current of typically 2.0 μAat 3.3 V. The ADT7420 is rated for operation over the −40°C to+150°C temperature range.Pin A0 and Pin A1 are available for address selection, giving theADT7420 four possible I2C addresses. The CT pin is an open-drainoutput that becomes active when the temperature exceedsa programmable critical temperature limit. The INT pin is alsoan open-drain output that becomes active when the temperatureexceeds a programmable limit. The INT pin and CT pincan operate in comparator and interrupt event modes.Product Highlights Ease of use, no calibration or correction required by the user. Low power consumption. Excellent long-term stability and reliability. High accuracy for industrial, instrumentation, and medical
