Is there a dual version of the THS4631?

Hi Chuck,

Unfortunately there is not. The OPA2810 is the only dual-channel FET-input voltage feedback amplifier. It's GBP is much less at 70 MHz vs the THS4631's 210 MHz. Can you tell us about the application and the key care abouts? What attracts you to the THS4631?

Thank you for your prompt reply!

Our criteria is:

SLew > 300V/uSec

PS +/-10V or higher

noise 8uV/rthz (some latitude here)

unity gain stable

>80MHz BW at G=1

Pkg Dual SOIC (some latitude)

oops - nV/rtHz not uV

Hi Chuck,

Is it necessary to be FET input?

If not, the THS4012 meets the above criteria. It is unity gain stable with a BW of 290 MHz, 310 V/us slew rate, 7.5 nV/rtHz noise, and comes in a dual SOIC package.
