• Is there a model for simujlating hte ADP121?

    I would like to simulate the ADP121 in my circuit. Is there a model for the ADIsim tool?

  • RE: CN0269

    Hello,

    Using 5V instead of 6V to power the board should not affect the measurement, but it is still recommended to use the board as specified.

    Looking at the schematic for the board found here it can be seen that the 6V voltage is being regulated to 5V…

  • RE: ADP3339 minimum input power and tolerance

    Hi Peter,

    Apologies for the delayed response, I'm still securing the board and ICs. Looking at this again though, I'd agree with Harry. It would be better to look at possible replacement parts that you could use in your circuit, pls see attached excel…

  • About overcurrent protection and selecting external diode

    Hi ,

    I have some questions about LDO products.

    #1,

    It looks like that ADI LDO products have current limitting protection, not current foldback.

    I just wondered why most LDO's current protection is current limitting.

    #2,

    Now I'm condering to…

  • RE: Best way to interface with ADXL346 from a 3.3V MCU?

    Hi YJ,

    The ADXL346 is a good choice for 2.5v or 1.8v processor IO signals.  The Vs signal on pin 14 is the analog supply voltage and should be connected to a quiet supply to get the lowest noise acceleration measurements.  There are parts like the ADP121…

  • RE: LDO用于数字负载、模拟负载以及射频负载需要关注哪些指标?

    LDO用于模拟和射频负载: 像ADP121和ADP130具有的低噪声和高电源抑制(PSR)性能对模拟环境中使用的LDO来说非常重要,因为模拟器件比数字器件对噪声更敏感。模拟LDO需求的主要来自无线接口要求——不损伤接收器或发送器,并在音频系统中不产生爆破音或嗡嗡声。无线连接非常容易受噪声的影响,如果噪声干扰到信号,接收器的效果将大打折扣。在考虑模拟线性稳压器时,器件要能抑制来自上游电源和下游负载的噪声,而且自身不增加噪声,这一点很重要。

    模拟稳压器噪声的测量值用电压有效值(rms)和PSR表示…

  • AD5542A pin description

    I plan to use AD5542A (16 pin TSSOP) in my design. Now I find the pin description on its datasheet is not compatible with the schematic of its evaluation board (ad5542_ug). 

    Could you verify the pin description of AD5542A?

  • ADI最新的EM流量计解决方案上线啦

    电磁流量计作为目前使用最为广泛的流量技术之一、液体流量测量中精度最高之一,你了解多少呢?

    先呈上【ADI最新的EM流量计解决方案】下载链接:http://h.analog.com/CN-APM-FLOWMETERff?ADICID=SOME_CN_P1657

    工业电磁流量计系统原理和典型架构

    电磁流量计的工作原理基于法拉第电磁感应定律。当垂直于磁场方向的导体以速度V做切割磁力线的运动时,导体的两端会产生一定的感应电动势E,通过检测该感应电动势的大小来计算液体流速变化。

    电磁流量计的特性包括无压力损耗…

  • LDO关键的指标和定义,您了解多少

    LDO咱们应用很多,但是关于这些基本指标和定义,其实很多小伙伴都似曾熟悉但又不能说出个所以然。这里整理出这些指标,并结合ADI的产品分享给大家,希望能与大家一起涨知识……

    输入电压范围:LDO的输入电压范围决定了最低的可用输入电源电压。指标可能提供宽的输入电压范围,但最低输入电压必须超过压降加上想要的输出电压值。例如,150mV的压降对于稳定的2.8V输出来说意味着输入电压必须大于2.95V。如果输入电压低于2.95V,输出电压将低于2.8V。


    接地(静态)电流:静态电流lq就是输入电流lIN和负载电流IOUT之间的差值…

  • RE: about ADRF6820

    Hi Henry,

    The impedance presented to the IQ output should be 200 ohms differential.  This is accomplished with resistive pads on our EVB, to  allow connection to a 50 ohm instrument and still present 200 ohms to the part.  This padding gives 17 dB of attenuation…
