NST1412 High-Accuracy, Remote and Local Temperature Sensor with I2C and SMBus Interface Datasheet (EN) 0.3 Product Overview  The NST1412 device is a high-accuracy, low-power remote temperature sensor with a built-in local temperature sensor. The remote temperature sensors are typically low-cost discrete NPN or PNP transistors, or substrate thermal transistors or diodes that are integral parts of microprocessors, microcontrollers, or field-programmable gate arrays (FPGAs). Temperature is represented as a 11-bit digital code for both local and remote sensors, giving a resolution of 0.125 °C. The two-wire serial interface accepts the SMBus communication protocol with up to six different pin-programmable addresses.  Advanced features [such as series resistance cancellation, programmable nonideality factor (η- factor), programmable offset, programmable temperature limits, and a programmable digital filter] are combined to provide a robust thermal monitoring solution with improved accuracy and noise immunity. The NST1412 is ideal for multi-location, high-accuracy temperature measurements in a variety of communication, computing, instrumentation, and industrial applications. The device is specified for operation over a supply voltage range of 1.7 V to 5.5 V, and a temperature range of -40 °C to 125 °C.
