I'm pretty new to analog electronic. I've been learning from appnotes and datasheets, and i've sometime seen reference of slew rate VS input level.
I've understood the effect of slew rate in audio, and i'm sure it's a really important…
Hi Mr. K,
I just want to clarify that bias current is the amount of current that the input circuitry of op amp requires for its proper operation. If the bias current of AD8641 is 260pA(max), then it is also the maximum current that the AD8641 can be…
Some of the other choices are:
ADA4610-2 if you need a dual
AD8510, and ADA4610-2
All of these are stable at gain of 1 for your voltage follower
how to get the below value from AD8641? from datasheet, In should be 0.5fA, right?
another question is about
in calculation, BW is equal to 10Kz. but in application MT-049, BW = 1.57*FCL, FCL = GBW / NoiseGain, this is my understanding,
Thank you for the answer. I'll try and implement that circuit and analyze the results. And yes, the output connected to ground was a mistake I made when I modified the schematics to post it here.
My design uses the other op amp present in the AD8642…
When I do a sim on the power supply, you have no attenuation with R20 and C20 until you get past
15 kHz. Try increasing R20 to 100 ohms and C20 to 10 uF. Would also help to put a small ceramic
(0.001-0.01uF) across C20.
The AD8541 is CMOS…
