SGM451
DESCRIPTION
The SGM451 device is a high-accuracy, low-power temperature sensor which integrates local and remote temperature channels. The remote temperature sensors connected with SGM451 are typically low-cost discrete NPN or PNP transistors, or substrate thermal transistors or diodes that are integral parts of microprocessors, microcontrollers, or FPGAs. The temperature is represented as a 12-bit digital code for both the local and remote sensors, giving a resolution of 0.0625℃. This device can measure the temperature of the local and remote diode sensors with an accuracy of ±0.5℃ (TYP). munication with the SGM451 is acplished via the two-wire serial interface which is patible with the SMBus munication protocol. Through this interface the SGM451 internal registers may be accessed.
The SGM451 has advanced features such as series resistance cancellation, programmable non-ideality factor (η-factor), programmable offset, programmable temperature limits, and a programmable digital filter...
