Hi I'm sure Michael will have an answer to this one but I'm trying to get the very fastest settling time for the THS3001 when used at x2.5 and x4 gain. on the datasheet slew rate is quoted at x5 gain as 25-75% and is presumably much slower 0-25 and 75-100%. My question is how do you avoid slew rate limiting for a full size step when the values outside 25-75% aren't published ? For example I could nicely limit input slew to correspond to 200V/uS which adds a 100% margin but I'll bet that still isn't enough to prevent slew rate limiting from say 10% - 0% and so settling time to 0.1% likely gets messed up. I note on the THS3001 datasheet it is for unity gain only and doesn't state input slew rate of source used for testing.
Does TI have any additional information I'd imagine the slew rate of source used for testing must be available ?
Also slew rate is specified at x5 gain, settling at x1 gain. Does TI have a graph of settling time Vs gain ? If not just values for x2.5, x4 and x5 would be extremely useful.
Thanks, Steve
