The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 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 DS18B20 can derive power directly from the data line ('parasite power'), eliminating the need for an external power supply.Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18B20s 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.How to Spatially Index 1-Wire® Sensors Using the MAXREFDES131 and DS18B20 FAQs: DS18B20ApplicationsConsumer ProductsIndustrial SystemsThermally Sensitive SystemsThermometersThermostatic Controls

The DS60 analog temperature sensor measures its own temperature and provides these measurements to the user in the form of an output voltage (VO) that is proportional to degrees centigrade. The output voltage characteristic is factory-calibrated for a typical sensitivity of +6.25mV/°C and a DC offset of +424mV at 0°C. Its operating temperature range is -40°C to +125°C, corresponding to an output voltage range of +174mV to +1205mV. The DS60 has ±2.0°C accuracy over a 0°C to +85°C temperature range and over the full +2.7V to +5.5V power supply range. Its accuracy is within ±3.0°C over the operating temperature range and full supply range. Because the output voltage is positive for the entire temperature range, there is no need for a negative power supply.The DS60's tiny size, low-current operation, and wide supply range make it ideal for use in battery-powered applications. To further reduce power dissipation, the DS60 can be powered by any logic gate output that is capable of sourcing 125µA, which allows the DS60 to be switched to a zero power standby state when the gate is forced to a logic 0.ApplicationsAutomotiveMedical EquipmentVending Machine

The ADXL335 is a small, thin, low power, complete 3-axisaccelerometer with signal conditioned voltage outputs. Theproduct measures acceleration with a minimum full-scale rangeof ±3 g. It can measure the static acceleration of gravity in tiltsensingapplications, as well as dynamic acceleration resultingfrom motion, shock, or vibration.The user selects the bandwidth of the accelerometer using theCX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins.Bandwidths can be selected to suit the application, with arange of 0.5 Hz to 1600 Hz for X and Y axes, and a range of0.5 Hz to 550 Hz for the Z axis.The ADXL335 is available in a small, low profile, 4 mm × 4 mm× 1.45 mm, 16-lead, plastic lead frame chip scale package(LFCSP_LQ).APPLICATIONS Cost sensitive, low power, motion- and tilt-sensing applications Mobile devices Gaming systems Disk drive protection Image stabilization Sports and health devices

The DS75LV low-voltage (1.7V to 3.7V) 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 DS75LV defaults to 9-bit resolution for software compatibility with the LM75. Communication with the DS75LV is achieved through a simple 2-wire serial interface. The DS75LV 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).ApplicationsAny Thermally Sensitive SystemCellular Base StationsOffice EquipmentPersonal Computers
