Hello. It is possible to use AD8541/2/4 if the input voltage greater than the supply voltage with external clamping diodes and a current limiting resistor?
May you please provide any data of AD8541/AD8542/AD8544's voltage noise in low frequency? I mean 0.1-10 Hz uV p-p.
I want to use it for EEG/ECG amplifier: exactly AD8542 - one op-amp for getting reference voltage (Vmid)- for a voltage follower in…
Hi
AD8541 revG datasheet say
Regarding about Large Signal Voltage Gain
Avo= 100V/mV @ Vs=2.7V, 3.0V
but Avo=20V/mV @ Vs=5.0V
Load is 100Kohm, so these are not a big difference, I think.
Could I see the "Avo vs Vs" feature?
Regard…
目前项目上用的运放、DAC、ADC基本都是ADI公司的产品，例如AD8541、AD8009、DAC7568、AD5312、AD7352、ADR4525等一系列产品，这里重点对应的一些参数进行说明，并简要叙说选型时的注意要点。中间有很多引荐了一些书籍、论坛的资料，不足之处还请各位指正批评。
PS：本帖讨论中如果有一些错误和模棱两可的地方，还请大侠们指正。小弟虚心接受，一起讨论。
1、运放供电。
single-supply Operation：2.7V to 5.5V，根据自己所需要的电路供电电压和输出电压…
1. I-V放大器的放大倍数是如何计算的，倍数就等于Rf的值吗？等同这里的10M ？
2. 如果是这样，那么设计的带宽范围很窄了，一般OP的单位增益带宽是10M的很大了，这样带宽几乎就1HZ了< 根据 f = 1/ (2pi R C) >，如果是？ 有什么方法可以改善带宽问题，谢谢
3. 在互阻放大器中，PIN二极管的有多种，一种正极接地，一种是负极接电源，如图中。这两者有什么区别？
Hi ,
Does anyone know if there is any Evaluation Board that has AD8541 + AD1972 on board?

Rookie,
There is nothing "wrong" with the AD8541 family. We split op amps into a precision group,
(less than 1 mV Vos, and less than 50 MHz) and a high speed group. (greater than 50 MHz).
The AD8541 family has some historical reasons why…
AAnand928 said:My understanding was input offset voltage was too low like 0.1mV
Where did you get this value from? In datasheet of AD8541/8542/8544 says that offset voltage equal 1mV typically
I have already said what needs to be done. You should limit…
