Hi, Michael/Kai:
I can remove C54 and see if it improves the waveform.
I do not understand what this mean "If the input goes to 0V on the low side, the output is saturating giving a recovery time issue to the waveform. We sometimes level shift the input…
Part Number: OPA2830 Other Parts Discussed in Thread: OPA830 , OPA2652 , OPA2822 , OPA2677 Hello, I am carrying out some reliability analysis on the OPA2830 and am having trouble finding information about the technology the chip was made with and am also…
Hello Kai,
All four of LM124s appeared the problem.The circuit works properly when i use AD8042 instead of LM124.Keep other components unchanged.The same is true for OPA830.
The tolerances of resistors are 1%,these's not enough to produce such a result.AD8042 a…
Hello,
In my experience, what is happening here is that when the major bits are flipping the ADC requires a large amount of transient current. I believe the OPA890 is incapable of providing this inrush current which is resulting in the dc error around…
Other Parts Discussed in Thread: OPA380 , OPA830 Hello friends,
We bought the OPA380 amplifier, and We want to simulate the whole system before we build it on PCB board, we found the OPA380 Pspice model from http://www.ti.com/product/OPA380 , could you tell…
Other Parts Discussed in Thread: OPA830 , LMH6550 Dear Sir,
I wanted to use a filter amplifier circuit using op-amp which pass up to 30MHz frequency.
As this application is based on radar, there is going to be a lot EMI-EMC, could you please suggest some…
Penghm, Is this inquiry related to your inquiry last month ( http://e2e.ti.com/support/amplifiers/high_speed_amplifiers/f/10/p/108255/382310.aspx#382310 )? TI does not have any rail-to-rail input (and output) op amps that have SR >300V/us. From our previous…

Other Parts Discussed in Thread: OPA4830 , LM324 , TINA-TI , OPA830 Hello,
I bought operational amplifier OPA4830. TSSOP14 package with 4 operational amplifiers inside. Datasheet: here
1st - OP AMP I use as a summer
2nd - integrator
3rd - trigger
4th - voltage…
