OPA858: OPA858

Hello,

I am looking for a buffer (Analog) with the following requirements:

1) Input voltage range: 0V to 0.9V

2) Fq: ~100MHz to 200MHz

3) Iq, Noise: We don't really care about it

4) VDD: We can provide any VDD between 0.9V to 3.3V (Or may be even higher if needed)

5) Should have very (very) low input capacitance. Kind of main requirement for this buffer. (May be less than 1pF?? I know its difficult to get it) If input doesn't have ESD protection, it will work for us.

6) Input is single ended and is not differential

I searched TIs website and found out two close ICs: OPA858 and THS4211/THS4215. Are these the two options available for our specs or do you suggest something else?

Thanks!
