Part Number: OPA1688 Other Parts Discussed in Thread: OPA1678 , OPA1637 , , OPA344 Tool/software: Hi Team,
Customer is trying to design the OPAMPs circuit for MEMS MIC output, and they are looking for a lot of OPAMPs for this design. So please review…
Hi Okang,
It looks like that these are two different active LPF filters.
OPA1678 Active Filter.TSC
OPA1678 Sallenkey Filter 07012025.TSC
I think that you want to minimize the total noise of the LPFs by balancing the R and C values in the active…
Part Number: NE5532A Other Parts Discussed in Thread: TLV9362 , OPA1678 , RC4580 Dear Team,
Do we have suitable solution can replace NE5532A?
For audio used and double input voltage +/-12V.
Many Thanks,
Jimmy
Part Number: PGA2311 Other Parts Discussed in Thread: OPA1678 , PGA4311
Tool/software:
Hello,
I'm using the PGA2311 in a product for approx. one year and it worked like a charm. No noticeable noise when changing volume. After the first two batches…
Hi Oksang,
We rarely do any customized chip design for a customer, however, I can pass on your inquiry to our marketing team.
I have informed you that above design is not in our business model. For instance, OPA1678 is one of low cost audio product…
Hi Lei,
Thank you for respond.
So, I must rather find the PWM mode Boost controller.
Iout will be about 20mA max. Or maybe lower? What do you think? According to my schematic below.
Thanks for recommendation TPS61377 but it is quite overkill.…
Part Number: OPA1632 Other Parts Discussed in Thread: OPA1678 , , NE5532 Dear team,
In professional audio application, there are a lots of people using the FDA such as OPA1632 to do the conversion of single to differential or XLR line out. For example…
Part Number: TIPD134 Other Parts Discussed in Thread: OPA1679 , OPA1604 , , OPA1678 , OPA1656 , TL074 I have developed a 3 band active audio filter, and I want to experiment with different op-amps to optimise the noise level. I have skimmed through TIPD134…
Hi Ruhland,
Sebastian Ruhland said: So my question would be is there any recommended replacement?
As you stated, OPA604 is still available, see the inventory status below.

Part Number: OPA325 Other Parts Discussed in Thread: OPA1678 Hello,
I built this amplifier and it works well even if it is more sensitive using a 120 pF piezo instead of 8.2 nF or adding a 120pF capacitor in series with the 8.2 nF piezo.
Now I receive…
