Part Number: OPA552 Other Parts Discussed in Thread: TINA-TI , OPA657 , OPA846 , OPA847 , OPA837 We would like clarification on section 8.2.2.3 of the corresponding (OPA55x) data sheet. It is poorly written, and we can not decipher the "formulae" for determining…
You are of course kidding me Paul,
Your example circuits are transimpedance designs where the source C is a big part of the response equations.
And actually, if I had to guess I would bet they are under 10pF and what I would probably due (lacking this…
Part Number: OPA857 Other Parts Discussed in Thread: OPA837 , OPA846 , OPA2837 Hi TI
1. I plan to use OPA857 in a wide input range application and I intend to control the gain in real time.
What is the response time at output when switching the Tz from…
Yes, that SBOA060 is very thorough (I believe by Jerry Graeme, who later published a very good transimpedance book under the Gain Technology name). What is in there are self limiting noise term equations. What we simplified in SBOA122 is we ignored the…
Part Number: ONET2591TA I found an application note, sboa122.pdf that discusses how to calculate the maximum achievable bandwidth for TIAs. It uses the OPA847, OPA846, OPA843 and OPA657 as examples. Do these same equations apply to the ONET2591TA. I have…
Part Number: OPA657 Hello
I've got a related question....to the connecting thread. I need to design a transimpedance amplifier with OPA657 (any better opamp from TI - with lower input bias current, please suggest, there is something better for the application…
Mickey,
We do not have an exact replacement for the CLC425, however depending on the exact needs the LMH6629 and OPA846 are possible substitutes.

Braulio,
Please see Page 13 and 14 of the OPA846 datasheet, section titled "Noninverting Low-Gain Compensation" to see how a decompensated amplifier may be made stable at lower gains.

Hello everyone
I need some technical support with the following issue: My team and me are developing a amplifier module for a SiPM…
Other Parts Discussed in Thread: OPA846 , TINA-TI I'm trying to design an Sallen-Key Filter around the OPA846 op-amp. My passband ends at 10MHz and I would like to be -3dB @ ~12MHz. My -45dB down point should be ~20MHz. This all seems doable with a…
