Analog Devices' digital temperature sensors, ADT7420 and ADT7320, achieve the highest accuracy of ±0.25°C over a temperature range of -20°C to +105°C. These fully calibrated, 16-bit resolution sensors eliminate the need to average results, leading to faster data measurement, higher precision control loops, improved energy efficiency, and reliability in industrial, instrumentation, and medical applications. The plug-in ready sensors require no additional signal conditioning or calibration. They are available with I2C (ADT7420) or SPI (ADT7320) digital interfaces, making them easy to integrate into various systems such as data acquisition, optical communications, environmental control systems, medical imaging systems, and food and pharmaceutical temperature monitors. The sensors also provide highly accurate system reference temperature measurement to reduce errors in software-based thermocouple cold-junction compensation applications and infrared imaging systems. They 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. 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).
