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

滤波器模式设计问题 +1
Answered

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？

再次咨询ADCMP567使用问题 0

抱歉，不知道如何在之前的帖子后面再次提问，只好重新提问之前的问题。目前我们设计了2种电路，帮忙看看是否有问题。图1的电路设计，ADCMP567 datasheet中 figure5 中的0V位置是否就可以表示为trig电平，也就是说，VH+/VH- 是以trig电平为参考基准的一个窗口。图2是否可以认为hysis电平为0. 图1 图2 图3

你好！我们目前关于ADMCP567设计的应用是：输入信号接+端，-端接一个触发电平，输入信号和触发电平进行比较，这种情况下，还能使用hysis功能吗？使用hysis功能的前提是输入-端必须接地，如figure 10 电路那样，我的理解是否正确？我们现在这种使用方式，正确的设计应该是按照figure 7 这样接，是否如此？谢谢

I’m trying to synchronize SYNC_CLK across three AD9914 devices. I’m using an AD9513 to provide the SYNC_IN signals, and I’ve already achieved same‑frequency, phase‑aligned SYNC_IN to all three chips. I also perform a common DAC calibration and IO_UPDATE...

ADHV4710恒流电路中增加开环增益输出电流被钳位的问题 +1
Answered

@ ALee687 如图所示的恒流源电路，只有去掉两个BAV199已经将ADHV4710的开环增益改为1（跟随器模式）才能有±1A的横流输出，如果开环增益增大输出电流就会被钳位，这是什么原因？

你好！我们使用adcmp567过程中发现有时有的芯片灵敏度较差，有的可以，不知道什么原因。想学习官方评估板的相关电路及PCB设计，但官方网站没有提供评估板的资料，这个能提供吗？谢谢！！

你好！新的产品选用ADCMP567 高速比较器，设计中有个疑问，比较器不需要latch功能，始终处于比较状态，并且需要使用hysiersi功能。按照规格书说明，如果不需要latch，将LE接VDD，LEB接VDD-2.0 即可，若使用hystersis,需要保持LE- LEB 是个负电压，LE和LEB该如何接法，目前使用规格书给出的典型应用电路，LE接地，LEB接hystersis电压，这个电路能正常使用比较功能吗？
