温度测量ADI

简介：

问：请推荐适合于K型热电偶的单电源运放
答： AD594/AD595 or AD8603.

问：ADI 的数字温度传感器是否有转换速度较快（〉100次/秒），精度较高，安装尺寸较小，可以用于仪器的型号（要求工作范围-20C~150C)？
答： Try AD7814.

问：在组建一个温度监控网络时，需要注意哪些要点？
答： When you set up temp control network, you have to decide which kind of bus you will adopt, what"s the accuracy and what should be measured locally, what should be remotelly. I think ADI"s parts can meet your requirement. For details, you can cont

问：使用温度产品应该注意些什麽问题呢？
答： You may pay attention to the temperature range and the amplifying circuit design for the small temperature coeffient sensors.

问：三种温度传感器,那种互换性能较好?成本较低?
答： Thermocouple and RTD is better on replacement, while thermist is not good at replacement. But thermist is better on price. However, digital sensors are good at both replacement and price. You can refer to this seminar file for detailed part# and spec and p

问：GE的温度产品与IC的温度产品的不同之处在哪？目前哪家的温度产品市场占有率最大呢？
答： According to the most recent Selantek report, Analog Devices is number one (33%), followed by National (27%), then Maxim (26%)

问：我的AD1674JN在中断方式下,与8051接口,但不能读出数据,请问我应该查哪里?能否给我一个标准程序?
答： Please contact our application center 800-810-1742.

问：AD7516使用外部电压基准源时,选用何种基准源比较合适?
答： If you use external REF, it can be from 1v to VDD. You"ve many choice on that REF, depending on your system design idea, like ADR42x/43x, ADR01/2/3, ADR158x, ADR39x/38x.

问：how to realize the interface between your IC of temperature measurement and CPU?
答： We"ve different series of temperature sensors. For example, AD7414 has I2C interface, AD7314 has SPI interface, TMP05/06 has PWM interface, while ADM1032/ADT7461, ADT751x/731x has I2C/SPI compatible interface.

问：how to calibrate your IC part? and how long it lasts for calibration interval? who shall charge the calibration? and how about the service fee if analogue does it?
答： We finished all factory calibration before it"s shipped to customer. If you mean real-time calibration, system designer need to do that, and ADI as IC supplier will not do that.
