Are there some alternative TI parts that could be a drop in replacement for a THS3062D? This is the SOIC 8 pin, no heat slug on the bottom.
Can be same slew rate or a little slower.
Max applied frequency would be <=1MHz.
thanks

Well this is a dual CFA device - the +/-15V supply limits your options considerably, if you were using it with+/-5V supply, many more options available.
Anyway, maybe the THS3122?
Apologies for not specifying the power supply aspect but yes, +/-5V.
I do not need +/-15V.
if you do come up with other choices then that would be great. otherwise we can close this out.
i do appreciate the help for the two parts you suggested.
Well there are quite a number of dual CFA's in the THS, OPA, and LMH lines,
OPA2694 is really fast, but not as much output drive,
OPA2684, is slower, but hold more constant BW over gain
etc, etc,
I needed to get into my parametric database every once in awhile, here you go - all the options from TI,
Oh and incidentally, these very early Dallas CFA parts had some difficulty on resolving the slew rate, for instance, the +/-5V spec table shows this,
And I frankly don't know what to make of these two plots, it is possible they are just seeing a non-slew limited rise time which then is constant with step size, that would then give a plot like this if you interpreted (wrongly) that to be a slewing edge.
And then even more oddly, there is this caveat to 900V/usec max. Yes, the CFA does draw a peaking transient supply current on the slewing edges, but this seems extreme,
They were struggling in this late 1990's timeframe to describe these newer (to them) device types.
