Q
I don't find any statement about the input protection of the AD8541/2/4 opamp,but in the datasheet of the AD8603 it is mentioned that the
inputs should be protected by resistors that keep input currents below 5 mA if
the input voltage…
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?

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…
Hi DNGZK,
1). Is the HMC1082LP4E Gain vs Temperature performance data given in the datasheet obtained with the temperature compensation network ?
There is no on chip compensation network for gain vs. temp.
The Vdet and Vref pins are a separate power detector…
