ADA4522-2供电问题 0
Not Answered

我现在使用ADA4522-2搭建了一个仪表放大器电路，我的输入信号范围是0-5V，所以我选择了ADA4522-2。规格书上说明供电电压要高于输入电压，我测试使用±5V供电，输入电压在3.5V以上，输出就开始不准了，与规格书说明的一致。所以我将电源更改为正电源+12V，负电源-5V，经过测试发现在输入在4V以上时，输出也开始不准了。我通过调节正电源的电压，调节到20V的时候，有问题的现象仍然存在。所以问题1：ADA4522-2的正负电源必须要对称吗，手里暂时没有匹配的负电源，还没有办法验证...

关于AD8132仿真 0
Answered

你好，在使用AD8132差分运放仿真时，有以一疑问，烦请解答 1、输入一个0.2Vpp的交流信号，经过电阻以后，怎么只有0.083Vpp？ 2、Vocm脚在实际使用时可以悬空吗？

Not Answered

Dear Analog Devices Support Team, We are evaluating the ADL8143 (ADL8143ACPZN, data sheet Rev. 0, 7/2024) and found what appears to be an inconsistency in the quiescent current (IDQ) vs. bias resistor (RBIAS) data: Table 8 (page 14) states that...

LTC1966输入隔直电容多大合适？ 0
Answered

上图是从LTC1966规格书里面摘录出来的，我现在的设计和该图一致，R1=R2=100K，VDD=5V，但是不Cc不知道该如何选？我现在要求测量10Hz-1000KHz，峰值电压为0-1V以内的正弦波信号的有效值，精度希望能达到0.1%，担心Cc太小会导致低频误差增大，请给我下设计规范。

ADHV4702增大输出电流，烧芯片问题 +1
Answered

想把ADHV4702的输出电流增大到100mA，采用VP2540和VN2540两个MOS管，按照datasheet上的图设计电路。仿真看步到问题。但是，在实验中，ADHV4702大概输出电流50mA超过1分钟就会烧芯片。已经烧了6pcs了，求帮忙

ADA4350现在是这样连接的，用的串行模式发送24bit命令切换开关，发送读取都可以成功，但是几种增益开关的效果和不接入的增益效果都是一样的，输入0.9ma结果是30多mv，输入10ma就变得宽了，能帮忙检查一下看看是原理图的问题还是哪里的问题吗

LTC1068典型应用里高通8阶滤波器采用了两个3a模式一个2b模式加一个3模式输出，但是我在数据手册（datasheet）找不到3a和2b模式的配置，请问是否有相关文件介绍其他模式的配置以及4阶以上滤波器串联配置的相关信息？
