SGM451
±1℃ Local and Remote Temperature Sensor with η-Factor, Offset Correction, Series-Resistance Cancellation, and Programmable Digital Filter
The SGM451 is a high-accuracy and low-power temperature sensor which integrates local and remote temperature channels. The remote sensor which is connected to the SGM451 is made by discrete transistors or diodes, which would be the integrated inside the MCU and FPGA. The SGM451 is a 12-bit device with a resolution of only 0.0625℃. This device can measure the temperature of the local diode sensors with an accuracy of ±0.3℃ (TYP) and remote diode sensors with an accuracy of ±0.8℃ (TYP).
Communication with the SGM451 is accomplished via the two-wire serial interface which is compatible with the SMBus communication protocol. Through this interface the SGM451 internal registers may be accessed.
There are many advantages of SGM451, such as cancelling the series resistance, calibrating the offset, changing the cutoff frequency of the digital filter, changing the limitation of temperature and non-ideality factor with programming. The above factors are significant to improve the accuracy of the SGM451.
The SGM451 is suitable for high precision temperature measurements in multiple locations in application system. The wide supply voltage range from 3.0V to 5.5V makes the SGM451 possible to use in a wide range of applications, including low power devices. The device operates over a wide temperature range of -40℃ to +125℃.
