In the fields of industrial control,consumer electronics and automotive electronics,the accuracy and reliability of temperature monitoring directly affect the system performance.SPI temperature sensor has become an important choice in high-precision temperature measurement scheme because of its advantages of high-speed transmission,strong anti-interference and simple interface.SPI(Serial Peripheral Interface)is a synchronous serial communication interface with full duplex and high speed.The temperature sensor based on SPI interface can directly output the temperature value through digital signals,reduce signal conversion links,and significantly improve the anti-noise ability and response speed of the system.This kind of sensor is usually highly integrated and small in size,which is suitable for scenes with strict requirements on space and power consumption.
GX122 is a temperature sensor that is fully compatible with SPI protocol,and is packaged in a compact SOT23-6 package.Its typical accuracy can reach 0.3℃in the range of-25℃to+85℃,and it can maintain the typical accuracy of 0.5℃even in the wide temperature range of-40℃to+125℃,showing stability.
GX122 SPI temperature sensor has many programmable functions,including resolution selection of 9-12 bits+sign bits,high and low temperature threshold setting and software shutdown mode,which can be flexibly configured by users according to actual applications.Its power supply range is 2.7V to 5.5V,the static current is only 50μA,and the standby power consumption is as low as 0.1μA,which is very suitable for battery-powered or low-power equipment.
Compared with similar products,GX122 SPI temperature sensor GX122 can still run reliably at 150℃and only needs an external pull-up resistor to work,which greatly simplifies the circuit design.Its conversion time is 30ms,which can meet most real-time monitoring requirements.
