The MAX31889 operates from a 1.7V to 3.6V supply voltage, and is a low-power, high-accuracy digital temperature sensor with ±0.25°C accuracy from -20°C to +105°C and ± 0.65°C accuracy from -40°C to +125°C. The MAX31889 has 16-bit resolution (0.005°C).The device uses a standard I2C serial interface to communicate with a host controller. Two GPIO pins are available. GPIO1 can be configured to trigger a temperature converison, while GPIO0 can be configured to generate an interrupt for selectable status bits.The MAX31889 includes a 32-word FIFO for the temperature data and also includes high and low threshold digital temperature alarms. The device is available in a 2mm x 2mm x 0.8mm, 6-pin, µDFN package.ApplicationsInternet of Things (IoT) SensorsPrecision Temperature MonitoringRTD Replacement

The DS1626 and DS1726 digital thermometers/thermostats provide temperature measurements and stand-alone thermostat capability over a -55°C to +125°C range. The DS1626 offers ±0.5°C accuracy from 0°C to +70°C and the DS1726 has ±1°C accuracy from -10°C to +85°C. The resolution of the measured temperature is user selectable from 9 to 12 bits. Communication with the DS1626 and DS1726 is achieved through a 3-wire serial bus.The DS1626 and DS1726 offer thermostatic functionality with three dedicated thermostat outputs (THIGH, TLOW, and TCOM), and overtemperature (TH) and undertemperature (TL) user-programmable thresholds stored in on-chip EEPROM. For stand-alone thermostat operation, TH and TL can be programmed prior to installation, and the DS1626/DS1726 can be configured to automatically begin taking temperature measurements at power-up. Table 1, in the full data sheet, summarizes the user-accessible registers. Figure 1, in the full data sheet, shows a functional diagram.ApplicationsAny Space-Constrained Thermally Sensitive ApplicationConsumer ProductsIndustrial ControlsThermostatic Controls

The DS18S20 digital thermometer provides 9-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18S20 communicates over a 1-Wire® bus that by definition requires only one data line (and ground) for communication with a central microprocessor. In addition, the DS18S20 can derive power directly from the data line ('parasite power'), eliminating the need for an external power supply.Each DS18S20 has a unique 64-bit serial code, which allows multiple DS18S20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18S20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems.ApplicationsConsumer ProductsIndustrial SystemsThermally Sensitive SystemsThermometersThermostatic Controls
