温度测量ADI

简介：

问：About the manufacturer of IR Sensor - Could you send this information to us after this seminar or can I get it from somewhere else ?
答： Sorry, we don"t have any information on this.

问：如果A/D芯片和传感器同处在被测温度环境中，会对精度产生影响吗？
答： ADC"s reference voltage will be effected by temperature. you must refer to ADC and/or Ref datasheet. AD Idigital output temperature sensor can simple you design.

问：Philips在Semiconductor sensor中的市场份额的情况如何？你前面提到的ADI、NS和Maxim市场份额比例是指半导体传感器，还是整个传感器领域？
答： I do not know the market share of Philips.
The market size quoted before is for IC Temperature sensors.

问：影响温度测量的精度和误差的因素有那些?
答： This is decided by the sensors, signal conditioing, ADCs and references you used.

问：在手机中,一般需要监测几路温度?
答： Normally one, for the RF VCXO.

问：Can I just use on ADT7461 to control two fan? Thanks!
答： You can use the ALERT and THERMAL signals to control two fans.

问：ADI有没有工业温度的测量技术?如炼钢温度等.这部分的温度如何测量?
答： We"ve various industrial temperature measuring solutions, AD594/5 are thermocouple amplifiers with cold-junction compensation, AD693 is 4-20mA sensor transmitter with precalibrated 100ohm RTD interface. For ironing temperature, as it"s high as 10

问：请问非典时期用来红外测温的测温枪又用到你们的芯片吗,他的误差大概是多少?
答： Yes, AD8607 is the sensor amplifier. Normally, the accuracy dependent on the IR sensor which is about +/- 2 degree C.

问：Can your IC part measure the temperature above 1200 degree?
答： Semicondutor temp sensor cannot be used under such high temp. But you can use thermocouple to implement this, AD594/5/6/7 can be used to implement the signal conditioning.

问：for non-contact temperature measurement, how to control the error in your product and what the error range is?

答： Usually, the non-contact thermal sensor is voltage output. The first stage amplifier is critical to choose. AD8618 "auto-zero" amplifier is very good on this applications to reduce the error. The error range dependent on the minimum output voltag
