The ADT7420 is a high accuracy digital temperature sensor offering breakthrough performance over a wide industrial range, housed in a 4 mm × 4 mm LFCSP package. It contains an internal band gap reference, a temperature sensor, and a 16-bit ADC to monitor and digitize the temperature to 0.0078°C resolution. The ADC resolution, by default, is set to 13 bits (0.
High performance Temperature accuracy ±0.20°C from −10°C to +85°C at 3.0 V ±0.25°C from −20°C to +105°C from 2.7 V to 3.3 V 16-bit resolution: 0.0078°C Ultralow temperature drift: 0.0073°C NIST traceable or equivalent Fast first temperature conversion on power-up of 6 ms Easy implementation No temperature calibration/correction required by user No linearity correction required Low power 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 Wide operating ranges Temperature range: −40°C to +150°C Voltage range: 2.7 V to 5.5 V P.
