温度测量ADI

简介：

问：请问：在0-100度范围内，数字温度传感器的分辨率最高能做到多少？什么型号？有无能做到0.001度的数字温度传感器？
答： It"s impossible to detect 0.001 degree using semiconduct sensor now. In -55 to 125 degree tempratue range, ADI can do the best accuracy is +-0.5 degree, for example ADT7301.

问：If we employ the IR sensor, which back end IC will be suggested from AD ?
答： AD8628, AD8603/07, ADuC834/16 are the parts we can provide.

问：我现在用8051驱动AD1674JN,在中断方式下不能读出数据,查询方式也不行,请问应该查哪里?能否给出一个标准程序?
答： Please call our application center: 800-810-1742

问：12位的数字温度传感器是否模拟温度传感器和12位AD的集成？
答： Refer to ADT7301 diagram, we can see there is 12bit ADC and temperature sensor.

问：贵司是否有与NS的LM75CIM和PHILIPS的LM75AD兼容或类似的温度传感器。
答： AD7414 and AD7416 are the high performance substitution of LM75.

问：Can I interface the SMBUS TO I2C bus without changing the software?
答： Normally yes. Except the minimum clock speed. I2C can low to zero but SMBus minimum speed is 10KHz.

问：What"s the different between THERM and ALERT limit? Does the THERM limit lower locate  in the ALERT limit range?
答： The THERM register provide you to set the measure temperature upper and lower windows. Once the temperature you measure is out of this window, the ALERT pin will send out a pulse to controller to ask do something for this out of temperature condition,

问：集成温度传感器如ad590的有哪些参数，比如稳定性，线性度，测量精度等等，分别表示什么意思？另外，我的项目设计要求达到温度控制精度达0.1度，则要求测量精度的数量级低于0.1度，如0.05度或0.01度，AD590能否达到此要求，若有，则有哪些型号？谢谢！！
答： You can find the specifications of AD590 in page 2 and 3 of it"s datasheet. AD590 can reach 0.5 to 5 degree. So it can not reach the accuracy you want. The temperature sensor of ADI can not reach 0.01 degree accuracy.

问：距离50cm之内（在空气中）温度在600攝度之内测量方案请指教溫请寄给我资料谢谢氣
答： I think you can use the infrared method. Then use AD8628 to amplify the signal, ADuC812 should be enough to implement the signal processing.

问：快速温度循环（temperature cycling）会引起温度传感器的时间漂移误差增大，那么请问是否同样对温度传感器的可靠性造成影响？例如贵公司的TMP01ES，工作温度范围是-55～+125摄氏度，快速温度循环下，会否导致其功能丧失等失效？
答： In temp cycling, the drift should be caused by the short time. But would not destroy the parts. When use TMP01 in temp cycling, it should work.
