The MAX30205 temperature sensor accurately measures temperature and provide an overtemperature alarm/interrupt/shutdown output. This device converts the temperature measurements to digital form using a high-resolution, sigma-delta, analog-to-digital converter (ADC). Accuracy meets clinical thermometry specification of the ASTM E1112 when soldered on the final PCB. Communication is through an I2C-compatible 2-wire serial interface.The I2C serial interface accepts standard write byte, read byte, send byte, and receive byte commands to read the temperature data and configure the behavior of the open-drain overtemperature shutdown output.The MAX30205 features three address select lines with a total of 32 available addresses. The sensor has a 2.7V to 3.3V supply voltage range, low 600µA supply current, and a lockup-protected I2C-compatible interface that make them ideal for wearable fitness and medical applications.This device is available in an 8-pin TDFN package and operates over the 0°C to +50°C temperature range.ApplicationsFitnessMedical

The MAX31730 temperature sensor monitors its own temperature and the temperatures of three external diode-connected transistors. The operating supply voltage is from 3.0V to 3.6V. Resistance cancellation compensates for high series resistance in circuit-board traces and the external thermal diode, while beta compensation corrects for temperature-measurement errors due to low-beta sensing transistors.All temperature channels have programmable temperature thresholds. When the measured temperature of a channel crosses the respective threshold, a status bit is set in the thermal status registers and the open-drain active-low THERM output asserts. A highest temperature register allows the master to obtain the temperature of the hottest channel.The 2-wire serial interface accepts SMBus protocols (write byte, read byte, send byte, and receive byte) for reading the temperature data and programming the temperature thresholds. Any one of eight available slave addresses can be selected using the address selection input (ADD), which can be connected to ground or connected to a grounded resistor.The MAX31730 supports 3.0V to 3.6V operation and is specified for a -40°C to +125°C operating temperature range and is available in a 10-pin µMAX® and a 12-pin, 3mm x 3mm TDFN package.ApplicationsCommunications EquipmentCPU, FPGA, and ASIC Die Temperature MonitoringServers

The MAX30207 is a low-power, high-accuracy digital temperature sensor with ±0.1°C accuracy from +30°C to +50°C and ±0.3°C accuracy from 0°C to +70°C. It provides a 16-bit resolution (0.005°C).The 2mm x 2mm x 0.75mm package design has extremely low thermal mass and can be mounted on a flex PCB with only two conducting traces, allowing for minimal thermal conduction to the system PCB and accurate temperature measurements.Data is transferred serially through the 1-Wire® protocol, which requires only one data line and a ground reference for communication. Power to the device is also provided using the same data line used for communication using parasite power circuitry inside the device. Each MAX30207 has its own unique 64-bit registration number factory programmed into the chip. This unique 64-bit registration number acts as the node address in a multidrop 1-Wire® network. In multidrop networks, optional GPIO pins may be used as address bits to identify each device's physical location.ApplicationsInternet of Things (IoT) SensorsMedical ThermometersWearable Body Temperature Monitors

The LTC2996 is a high accuracy temperature sensor with adjustable overtemperature and undertemperature thresholds and open drain alert outputs. It converts the temperature of an external diode sensor or its own die temperature to an analog output voltage while rejecting errors due to noise and series resistance. The measured temperature is compared against upper and lower limits set with resistive dividers. If a threshold is exceeded, the device communicates an alert by pulling low the correspondent open drain logic output.The LTC2996 gives ±1°C accurate temperature results using commonly available NPN or PNP transistors or temperature diodes built into modern digital devices. A 1.8V reference output simplifies threshold programming and can be used as an ADC reference input.The LTC2996 provides an accurate, low power solution for temperature monitoring in a compact 3mm × 3mm DFN package.Applications Temperature Monitoring and Measurement System Thermal Control Network Servers Desktop and Notebook Computers Environmental Monitoring

The DS75 digital thermometer and thermostat provides 9, 10, 11, or 12-bit digital temperature readings over a -55°C to +125°C range with ±2°C accuracy over a -25°C to +100°C range. At power-up, the DS75 defaults to 9-bit resolution for software compatibility with the LM75. Communication with the DS75 is achieved via a simple 2-wire serial interface. Three address pins allow up to eight DS75 devices to operate on the same 2-wire bus, which greatly simplifies distributed temperature sensing applications. The DS75 thermostat has a dedicated open-drain output (O.S.) and programmable fault tolerance, which allows the user to define the number of consecutive error conditions that must occur before O.S is activated. There are two thermostatic operating modes that control thermostat operation based on user-defined trip-points (TOS and THYST).A block diagram of the DS75 is shown in Figure 1 and detailed pin descriptions are given in Table 2.ApplicationsAny Thermally Sensitive SystemCell Phone Base Stations Office EquipmentPersonal Computing

The LTK001 is a thermocouple amplifier supplied with a matched cold junction compensator. By separating the amplifier and compensator functions, the problem of compensator temperature rise is virtually eliminated. The compensator is a selected version of the LT1025 cold junction compensator. The amplifier, which is also available separately as LTKA0x has been specially selected for thermocouple applications. It has low supply current to minimize warmup drift, very low offset voltage (<35µV), high gain, and extremely low input bias currents (<600pA) to allow high impedance input filters to be used without degrading offset voltage or drift.Matching of the kits is accomplished by separating the compensators and amplifiers according to the polarity of their initial (room temperature) errors. This eliminates the need to sum the errors of the two components to find the worst-case error.The LTK001 has direct thermocouple outputs of 60.9µV/°C (E), 51.7µV/°C (J), 40.6µV/°C (K, T), and 5.95µV/°C (R, S). It also has a 10mV/°C output which can be scaled to match any arbitrary thermocouple.For multiple thermocouple applications using one compensator, amplifiers may be ordered separately (LTKA0x), still matched to the compensator.Applications Thermocouple Cold Junction Compensation
