How to extend ADHV4710 output amplitude 0
Suggested Answer

Hi, folks, Since the ADHV is great in almost everywhere, like Band Signal Bandwidth(neglect the gain), high frequency(2MHz around), and super Slew Rate(compared with ADHV4702, which have wider powersupply, but much less SR), except one point, the...

ada4254的断线检测功能问题 0
Not Answered

我在使用ada4254的断线检测功能时出现一个问题我先对WB_DETECT寄存器(寄存器0x07)进行配置闭合SW_F1和SW_F2开关，之后读取ANALOG_ERR（0x04）寄存器的bit 4(WB_ERR)位。我将输入信号断开，能读到WB_ERR变为1，表示检测到了断线；此时仍保持输入信号的断开状态，对WB_ERR写1以清除该位错误，之后再持续读取WB_ERR位的状态，发现它他始终为0，无法对应此时输入信号仍是断开状态。请问，这是芯片的功能如此还是我使用方法有误？如果我想持续监测一个输入信号是否在断线之后仍保持断开的状态...

how to design a voltage amplifier with the capability of high speed(2MHz or above) and high slew rate(160Vpp) 0
Not Answered

I know we maybe need discrete mosfet or BJT to be the driver, and high speed op amp to be the controller. And found some solutions, but too slow frequency, like 100k or 200kHz, rarely can reach 1MHz while the amplication is about 150Vpp. Having tried...

ADA4522-2供电问题 0
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...

DC2414A-3.PCB评估板打不开怎么办 0
Answered

这个PCB文件我用AD22、PADS Layout Viewer最新版和Protel 99se都打不开。是否能获取一份可以打开的文件或者说有什么指定软件才能打开，又或者告知这个PCB文件使用的什么软件绘制的。迫切需要查看pcb,万望回复。

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？
