Part Number: OPA4820 Hello,
Do we have data on the 2nd and 3rd Harmonics of the OPA4820 look like up to 60MHz? I only see up to 10MHz in the datasheet.
details of the signal and desired performance are below
- 60MHz differential sinewave
- Amplitude…
Part Number: LMH32404 Other Parts Discussed in Thread: OPA4820 , LMH32401 , TLV3544 Tool/software: If using photodiodes as current sources, would the simplest way to AC-couple for ambient light filtering be via in-series capacitors prior to the input pin…
Hello Gerald,
Yes, high speed amplifier group is the correct place for this type of application. Michael already gave really good suggestions. I will add a couple more below and here is an app note for NTSC composite video applications .
LMH6612 (closest…
Hello Arik,
The OPA4820 should meet this requirement (210 MHz in G=+2). Is the customer looking for small-signal BW or large-signal BW? The LMH6722 is a current feedback amplifier and can also meet the BW in a gain of +2 requirements. Its noise is slightly…
Other Parts Discussed in Thread: PGA113 , OPA4820 Hello Dear Friends and Masters.
im using PGA113 for first time in my project, i connected the output of one opamp (OPA4820) to PGA using one 100nf bypass Cap to CH1 .
i leaved the CH0/CAL pin floating. my…
Hi Jonathon,
I'm sorry your question missed our attention. The op amp you linked OPA4820 should work fine. For your application there are many amplifiers that would be suitable with only subtle differences in performance. You may want to consider…
Other Parts Discussed in Thread: LMH6722 , OPA4820 looking for a QUAD OP.AMP TSSOP14 package ±5V PS, BW=150MHz at G=2(300G/BW) .We use today OPA4830IPW, I need IC instead of LT6559
Edward,
I tried to respond to your earlier post and was having some trouble with the forum, so now I'll address both:
I suspect the problem you may be having with the OPA4820 is mostly a matter of how you're building the prototype. Remember I cautioned…
Other Parts Discussed in Thread: OPA847 , LMH6629 , OPA684 , BUF602 , OPA4820 In my application, I have a voltage signal that is like a radar pulse.
It is at a 5MHz sine wave, lasts a few microseconds, and is (as far as I can tell) about 1uV in amplitude. I need…
