ADT7320/ADT7420 Digital Temperature Sensors

Analog Devices Inc. ADT7320/ADT7420 Digital Temperature Sensors are ±0.25°C accurate SPI/I²C digital temperature sensors that provide excellent performance over a -40°C to +150°C temperature range. The ADT7320/ADT7420 Digital Sensors include an internal band gap reference, a temperature sensor, and a 16-bit ADC to monitor and digitize the temperature to a resolution of 0.0078°C. Using the SPI/I²C serial interface, designers can change the default ADC resolution set at 13 bits (0.0625°C) to meet their application requirements. Operating at 3.3V, the ADT7320/ADT7420 sensors are guaranteed to operate over the 2.7V to 5.5V supply voltage range with a typical supply current of 210μA. The ADT7320/ADT7420 sensors include a shutdown mode that powers down the device and delivers a typical shutdown current of 2μA at 3.3V. The Analog Devices ADT7320/ADT7420's high accuracy makes the sensors ideal for instrumentation, industrial, and medical applications.

Digital Temperature Sensors

Analog Devices Inc. Digital Temperature Sensors are part of a wide range of temperature sensing and control applications that offer many design alternatives. These solutions offer in-depth design information and circuits for building thermal sensing signal chains using the most popular thermal sensors. Usually, the first step in designing a thermal sensing and control system is to determine the temperature range that must be sensed as well as the operating environment. The next step is selecting a thermal sensor. There are four main types of thermal sensors: silicon, thermistor, RTD, and thermocouple. ADI provides either complete signal chain solutions or integrated ICs that can take the thermal transducer signal, process it, and provide either an analog or digital communication path back to the control device.

Analog Temperature Sensors

Analog Devices analog temperature sensors deliver current or voltage output proportional to the absolute temperature with an accuracy rating of up to ±1°C. The analog temperature sensors eliminate the need for external calibration with minimal signal conditioning/conversion circuitry. ADI offers an expansive portfolio of analog output temperature sensors that are suitable for a broad range of applications. To meet diverse design requirements, the ADI temperature sensors are available in multiple package options.
