ANALOG DEVICES ADT7420UCPZ-R2

Product Overview

The ADT7420UCPZ-R2 is a high accuracy Digital Temperature Sensor offering breakthrough performance over a wide industrial range, with 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 (0.0625°C). The ADC resolution is user programmable mode that can be changed through the serial interface. The ADT7420 has a shutdown mode that powers down the device and offers a shutdown current of typically 2.0 μA at 3.3 V. Pin A0 and Pin A1 are available for address selection, giving the ADT7420 four possible I²C addresses. The CT pin is an open-drain output that becomes active when the temperature exceeds a programmable critical temperature limit. The INT pin is also an open-drain output that becomes active when the temperature exceeds a programmable limit. The INT pin and CT pin can operate in comparator and interrupt event modes.
  • High performance temperature accuracy ±0.20°C from -10 to +85°C at 3V
  • High performance temperature accuracy ±0.25°C from -20 to +105°C from 2.7 to 3.3V
  • 0.0078°C 16-bit Resolution
  • 0.0073°C Ultra-low temperature drift
  • NIST traceable or equivalent
  • Fast first temperature conversion on power-up of 6ms
  • Easy implementation
  • No temperature calibration/correction required by user
  • No linearity correction required
  • Low power power-saving 1 sample per second (SPS) mode
  • Low power 700µW typical at 3.3V in normal mode
  • Low power 7µW typical at 3.3V in shutdown mode
  • Programmable interrupts critical over-temperature interrupt
  • Programmable over-temperature/under-temperature interrupt
