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 I2C (ADT7420) or SPI (ADT7320) digital interfaces, both of 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 μA (typical). The sensors include a low power, one-sample-per-second mode that draws only 46 μA (typical) at 3.3 V and also offer a shutdown mode that reduces supply current to just 2 μA. Programmable options include over/undertemperature and critical temperature indicators. ADI offers a complete range of analog and digital temperature sensors with the diversity to be used in a broad range of applications. For more information, visit www.analog.com/temp-sensors.
