Other Parts Discussed in Thread: THS3120 Hi,
I am planning to use THS3120 to measure PSRR of my low-drop-out regulator. Moreover, I bought THS3120 EVM and I think they will deliver it to me tomorrow.
However, what I do not understand from http://focus…

I cannot find a direct replacement for the AD844 for its BW and Slew-rate combination. The THS3091 has greater BW and slew-rate. The THS3120 has slightly larger BW but smaller slew-rate than the AD844.
The OPA637 will be a good replacement for the AD845…
Hello Andrey,
If you use a 4:1(turns) transformer then the load to the amp would be 20*16 = 320 Ohms and the votlage swing would be 0.5 * 4 = 2V.
This is what transformers are designed for.
For a 1:1 transformer I agree the amps I suggested are not the…
Hello Ken and Seb,
I've put together a spreadsheet of the most promising devices for your review and consideration. This spreadsheet uses your conditions:
Cin= 80pF
Required Bandwidth > 10kHz (I've used 100kHz to allow margin)
Min / Max input…
