Part Number: OPA4228 Tool/software: The chip has different latency at low and high frequencies (above 5k). The delay is larger at low frequency。
Before the application of equipment only low frequency is OK, now is to achieve low frequency and high frequency…
Part Number: OPA4228 Other Parts Discussed in Thread: LM3886 , , OPA1656 Hello,
I'm looking to design an analog based 3-band active tone control to be used as a pre-amp that will feed into the input of an LM3886 amplifier circuit. I saw the tone control…
Other Parts Discussed in Thread: OPA4228 , LM324 , OPA228 , OPA227
I have a phase circuit that I have designed that uses four Op Amps to take an AC Input in the range of 50-60hz and then produce copies of that signal in but each phase shifted by 120…
Other Parts Discussed in Thread: OPA4228 , OPA228 Is it safe, under all conditions, to strap any unused OPA4228 amps in unity gain follower configuration (OPA4228 is stable with gain>5)?
If not, how should unused amps be configured?

Hi Yordan,
the OPA4228 is a decompensated version of the OPA4227 and is very much faster than the OPA4227. But the OPA4228 can only be used with a gain greater than 5. Theoretically, you could replace the first OPAmp in the circuit (U3 in my last simulation…
Hi Hui,
Hui Cao22 said: Does your company recommend a chip with the same package but lower delay?
Please provide us the schematic and timing requirements on the design. Without the information, I am unable to provide you any suggestions. The Vout…
Hi Thomas,
I am going to take a guess what your question is. Kai is correct about his reply.
For quad op amp package that is similar to OPA37 in performance may be OPA4227/OPA4228, OPA2211 is only dual.
Please let me know if this is what you are…
ser,
The LM1036 was released over 20 years ago. It is no longer available.
Here are two starting points to get the same function.
OPA4228 datasheet, see section 8.1.5 Three-Band Active Tone Control (Bass, Midrange, and Treble)
Alos see,
Jean, OPA828 with GBP of 50MHz and Vos of +/-150uV would be the fastest precision op amp but OPA189 (GBP of 14MHz) has highest precision of max Vos of +/-3uV. Hoever, neither one comes as a quad package. For higher bandwith quad version, we have only…
