Morning,
It is hard to tell specifics on this particular plot and for a part that old, the much new OPA2837 shows kind of an incredible plot - essentially, these are network analyzer measurement driving one channel but measuring what comes through on…
Well Claudio,
At the physical level, it is critically important for good settling time to have Q<0.7 design and stay out of slew limiting on the transition, discussed some of this here,
Another device similar to the OPA2626 is the OPA2837. That…
Well there are plenty of parts with higher slew rate than the x350
1st, do you need RRIO? if so that limits your choices pretty quickly - if you can use negative rail in, RRout, looks at the OPA2837.
You could look at the OPA2810, if you need RRIO…
There is no current limit in the OPA2836. The iimproved OPA2837 has slightly more output current, might not be a Q1 version though,
The output current in the AbsMax table is a continuous DC current that is set by a metalization migration concern. This…
Also if I look at the channel mismatch section of that really good10 little lessons slide deck it notes the mismatch based specs will not be any better matched on a dual than a single - that makes intuitive sense but I will say in working on the OPA2837…
Yes Hasan, you could go to the various hi rel options for that temp range, but
Most of the newer parts offer -40 to 125 as their standard temp range, like the OPA2837
And actually, the OPA2810 might be the part to look at with similar spec range and…
Part Number: OPA357 Other Parts Discussed in Thread: MUX509 , OPA837 , OPA2837 Hi,
We need to sense 2 AC inputs (2Vpp, 2MHz). We have 2 options -
1. Use 2 separate OPA357s and tie their 2 outputs together and pass to next stage. We will use shutdown…
Thanks Anton, for the effort to deliver a TINA file, looking at the single supply one,
1. This is a quite old file (2016?). It will of course not work with a 0V on the negative supply given the 0.8V headroom required on this device, If you add a negative…
So you are doing a buffer?
A 10MHz 2Vpp sinusoid requires a peak dV/dT of 62.8V/usec.
If you can use a 5V part, use the OPA2837 - if you need a 10V total supply, use the OPA2890
This sure looks confused
1. The LMH6559 is a low output impedance voltage source - why are you using such large R's in the OPA656 - is this like a a test circuit for an eventual transimpedance design,
2. When you switch to 100Mohm on the buffer input…
