• RE: ADR445 Trim Pin Voltage range and design

    Hi cm_ele_egr,

    I am happy to help you understand ADR445 user trim capability. After reviewing ADR445 design schematic the expected trim output voltage range is 5.05 V to 4.74 V. Within trim configuration the R1 was set to 100K Ohm. Please note the expected…

  • ADR445的输出为5.9V左右?

    各位好!我想向大家请教一个ADR445的使用问题。

    我用ADR445做5V的参考基准,它的电路是按照数据手册提供的基本电路画的,输入端两个去耦电容(10uF 和0.1uF),输出端一个0.1uF电容。输入是电池提供的9V(实测8V到9V间),但是输出是5.9V左右,这与标定的5V输出相差太远了我的芯片是申请的样片,两片我都试过,都是这个输出。我也是试过用12V的线性电源,输出也是5.9V左右

    我想请教下大家这是什么原因。


  • 请问ADR445输出怎么是5.9V左右,ADR441输出怎是3.6V左右?

    电路图如附件,我开始用15V的输入,输出是5.9V,换成12V的输入输出还是5.9V左右,只有当出入是5.2V时,输出才是5V,不知道为什么?用ADR441,输出是3.6V左右,而且输入电压越大输出也就越大?ADR445的输出我用示波器测了,尽然是锯齿波?

    另为手上有一个是TI公司的REF102,直插的,输出10V很稳定。

    还请ADI公司工程师能帮解释一下,难道是我的电源文波大的缘故??

  • RE: AD5791使用问题

    ADR4455V基准源。请问是使用该基准源来产生正负10V基准源的吗?若是如此,建议检查在满量程输出的时候由ADR445输出转化而来的正负10V基准电压水平是否正常。

  • RE: hi  I am using AD5791 with control word "000000000000000000000100" . I Get  2 mV at LSB. Is that correct ? Is my control word setting is correct?

    Hi,

    LT1002 is an operational amplifier. Can you please clarify how you used this as the reference? what is your input to the amplifier? could send the connections you've made?

    You could refer to the AD5791 board user guide for different reference…

  • Universal Definition for "No Connect" or "NC"?

    I am currrently working with the AD8624 and ADR445, but I would like to know if the answer to this question is the same for all Analog Devices products.  If a pin is labeled "NC" or "No Connect", does that mean it has no internal connection, and it could…

  • AD7176-2 and CN0310

    I have some questions about Figure 2. of CN0310.

    How much is RMS NOISE in the case of output data rate 5ksps ?

    Is the horizontal scale correct ?

    I have never seen x100 log scale.
