World's Highest Performance Digital Temperature Sensors Flagship Products • Industry-leading accuracy; max accuracy • Operating temperature range: -40°C to +150°C • No self heating or linearity correction required • Power saving mode (1 SPS) • Critical temperature indicator • Over/undertemperature interrupt • 16-lead LFCSP RoHS-compliant package • Medical equipment • Cold junction compensation • Industrial control and test • Food transportation and storage • Environmental monitoring and HVAC Analog Devices' Digital Temperature Sensors Achieve Highest Accuracy of ±0.25°C Over Industry's Widest Temperature Range The ADT7420 and ADT7320 digital temperature sensors are fully calibrated, 16-bit resolution, high linearity sensors that achieve ±0.25°C accuracy over a -20°C to +105°C temperature range. The higher accuracy eliminates the need to average results, ensuring faster data measurement, higher precision control loops, and improved energy efficiency and reliability in industrial, Instrumentation, and medical applications. The ADT7420 and ADT7320 digital temperature sensors are plug-in ready and require no additional signal conditioning or calibration. The offerings are available with PC (ADT7420) or SPI (ADT7320) digital interfaces, which allow system designers to easily integrate the devices into data acquisition, optical communications, environmental control systems, medical imaging systems, or food and pharmaceutical temperature monitors. The new digital temperature sensors also provide highly accurate system reference temperature measurement to reduce errors in software-based thermocouple cold-junction compensation applications and infrared imaging systems. These digital temperature sensors are guaranteed to operate over supply voltages from 2.7 V to 5.5 V with an operating temperature range of -40°C to +150°C. Operating at 3.3 V, the supply current is 210 jxA (typical). The sensors include a low power, one-sample-per-second mode that draws only 46 jxA (typical) at 3.3 V and also offer a shutdown mode that reduces supply current to just 2 (xA. Programmable options include temperature indicators. ADI offers a complete range of analog and digital temperature sensors with the diversity to be used in a broad range of applica- tions.
