Part Number: OPA2145 Other Parts Discussed in Thread: LF412 , , TL082H , LOG114 , TL072 , OPA397 , OPA392 , OPA197 , OPA192 , LMP7721 , OPA828 , OPA2392 , LMP2012 Hi Experts,
We are working on a solution with log amplifier and thinking of developing…
Hi Dylan,
it's essentially the same. Often (but not always) "Aol" is specified without load resistance and "Avd" is specified with defined load resistance.
Keep in mind, that the datasheet contains two totally different OPAmps, the older TL082 and…
Part Number: TL081H Other Parts Discussed in Thread: TL081 , TL072 , TL072H , OPA1642 , TL052 , , TL082 , TL082H
According to this technical note , The old JFET TL072 had increasing distortion with increasing source impedance, which I assume was also…
Part Number: RC4558 Other Parts Discussed in Thread: LM358B , TL072H , TL082H , LM358LV The customer is using RC4558IDR. they want to figure out that when Vcc- is GND, is the minimum voltage at Vcc+=5V?
or the minimum voltage should be 10V =(+5V - …
Hey Maggie,
There are a couple changes you can make to see the stability of this circuit, however the TL082 model is fairly outdated and may not accurately model stability.
There is a newer version of this device, the TL082H, which I will use for…
I was indeed looking at the TL082H since it is looking better specified.
The TL082 is more vague.
But table 6.4 has the following: "ESD Ratings: All Other Devices", which sounds that the non H version also have ESD diode protection.
If Vcc is less…
Klaus,
Here are bench results for VOUT vs. VIN for unity gain, no load, Vs = 10V (nice round number) ; for several samples
Starting with TL082, This is phase reversal.
Now TL082H, much improved but not great (because it's not RRI)
Zooming…
