The ADT7311 is a high accuracy digital temperature sensor in a narrow 8-lead SOIC package. It contains a band gap temperature reference and a 16-bit ADC to monitor and digitize the temperature to a 0.0078°C resolution. The ADC resolution, by default, is set to 13 bits (0.0625°C). The ADC resolution is a user programmable mode that can be changed through the serial interface.The ADT7311 is guaranteed to operate over supply voltages from 2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typically 210 μA. The ADT7311 has a shutdown mode that powers down the device and offers a shutdown current of typically 2 μA. The ADT7311 is rated for operation over the −40°C to +150°C temperature range.The CT pin is an open-drain output that becomes active when the temperature exceeds a programmable critical temperature limit. The default critical temperature limit is 147°C. The INT pin is also an open-drain output that becomes active when the temperature exceeds a programmable limit. The INT and CT pins can operate in either comparator or interrupt mode.PRODUCT HIGHLIGHTS Ease of use, no calibration or correction required by the user. Low power consumption. Excellent long-term stability and reliability. Packaged in an 8-lead SOIC, RoHS-compliant package.APPLICATIONS Battery management Climate control and infotainment Lighting Powertrain Thermocouple cold junction compensation GPS 

The AD22100 is a monolithic temperature sensor with on-chip signal conditioning. It can be operated over the temperature range -50°C to +150°C, making it ideal for use in numerous HVAC, instrumentation and automotive applications.The signal conditioning eliminates the need for any trimming, buffering or linearization circuitry, greatly simplifying the system design and reducing the overall system cost.The output voltage is proportional to the temperature times the supply voltage (ratiometric). The output swings from 0.25 V at -50°C to +4.75 V at +150°C using a single +5.0 V supply.Due to its ratiometric nature, the AD22100 offers a cost effective solution when interfacing to an analog-to-digital converter. This is accomplished by using the ADC's +5 V power supply as a reference to both the ADC and the AD22100 (See Figure 2 of the datasheet), eliminating the need for and cost of a precision reference to both the ADC and the AD22100 eliminating the need for and cost of a precision reference (see Figure 2).APPLICATIONS HVAC systems System temperature compensation Board level temperature sensing Electronic thermostatsMARKETS Industrial process control Instrumentation Automotive

The AD22105 is a solid state thermostatic switch. Requiring only one external programming resistor, the AD22105 can be set to switch accurately at any temperature in the wide operating range of -40°C to +150°C. Using a novel circuit architecture, the AD22105 asserts an open collector output when the ambient temperature exceeds the user-programmed setpoint temperature. The AD22105 has approximately 4°C of hysteresis which prevents rapid thermal on/off cycling.The AD22105 is designed to operate on a single power supply voltage from +2.7 V to +7.0 V facilitating operation in battery powered applications as well as in industrial control systems. Because of low power dissipation (230 µW @ 3.3 V), self-heating errors are minimized and battery life is maximized.An optional internal 200 k(ohm) pull-up resistor is included to facilitate driving light loads such as CMOS inputs.Alternatively, a low power LED indicator may be driven directly. APPLICATIONS Industrial process control Thermal control systems CPU monitoring Computer thermal management circuits Fan control Handheld/portable electronic equipment
