nnnnAnalog Devices' Digital Temperature Sensors Achieve Highest Accuracy of ±0.25°C
nnnnOver Industry's Widest Temperature Range
nnnnThe ADT7420 and ADT7320 digital temperature sensors are fully calibrated, 16-bit resolution, high
nnnnlinearity sensors that achieve ±0.25°C accuracy over a -20°C to +105°C temperature range.
nnnnThe higher accuracy eliminates the need to average results, ensuring faster data measurement,
nnnnhigher precision control loops, and improved energy efficiency and reliability in industrial,
nnnnInstrumentation, and medical applications.
nnnnThe ADT7420 and ADT7320 digital temperature sensors are plug-in ready and require no
nnnnadditional signal conditioning or calibration. The offerings are available with PC (ADT7420) or SPI
nnnn(ADT7320) digital interfaces, which allow system designers to easily integrate the devices into data
nnnnacquisition, optical communications, environmental control systems, medical imaging systems, or
nnnnfood and pharmaceutical temperature monitors. The new digital temperature sensors also provide
nnnnhighly accurate system reference temperature measurement to reduce errors in software-based
nnnnthermocouple cold-junction compensation applications and infrared imaging systems.
nnnnThese digital temperature sensors are guaranteed to operate over supply voltages from 2.7 V to
nnnn5.5 V with an operating temperature range of -40°C to +150°C. Operating at 3.3 V, the supply
nnnncurrent is 210 jxA (typical). The sensors include a low power, one-sample-per-second mode that
nnnndraws only 46 jxA (typical) at 3.3 V
nnnnand also offer a shutdown mode
nnnnthat reduces supply current to just
nnnn2 (xA. Programmable options include
nnnnover/undertemperature and critical
nnnntemperature indicators.
nnnnADI offers a complete range of
nnnnanalog and digital temperature
nnnnsensors with the diversity to be
nnnnused in a broad range of applica-
nnnntions. For more information, visit
