Part Number: OPA4131 For the same batch, the silk screen printing on the back is inconsistent, please help to check the reason, thank you, is there a corresponding document des cription
Hi Paul,
Thank you for your reply.
I understand PSpice model of TL3474 is not enough to confirm pulse response.
I'll share your information to use OPA4131 or OPA4172 instead with my customer.
I'd like to confirm just in case, is there a plan to improve…
Other Parts Discussed in Thread: OPA4134 , OPA1644 , OPA4131 , TL084 Hello! It is necessary to replace the operational amplifiers TL084 in the active crossover of the Dynaudio BM6 Mk3 studio monitor amplifier by higher quality ones. Can you please tell us…
Other Parts Discussed in Thread: OPA4131 , ACF2101 , OPA2107 Hello,
I had a few questions about the spectrum I'm measuring at the output of my buffer circuit with the switched integrator, an ACF2101. The buffer amplifier is the OPA4131.

Other Parts Discussed in Thread: OPA4131 , TINA-TI , OPA131 , OPA27 Hey,
I'm now working on a trans impedance circuit using OPA4131(please see the following schematic), the bandwidth is set pretty low @ 330Hz, but the circuit oscillates (~3MHz) with a 10…

Richie,
Thank you for this thorough description of you applicaiton needs. For your application issue I would recommend that you use a Bessel, Bandpass filter that uses the Sallen-Key topology. This filter would look like.
The center frequency for this…
Hello Bruce,
Thanks for the quick reply.
I measured the photo diode resistance over the temperature range involved and it always remained > 100MOhm
The OPA4140 photodiode amplifier (U1) was followed by another opamp OPA4131 (U2) for summing the 4…
