THS4520 stability with gain +1

Other Parts Discussed in Thread: THS4520

I would like to use THS4520 for active filter passband in multiple feedback configuration. So the amp feedback will be shorted by capacity at very high frequencies. Please can you advice me if it is good idea? Or could the amplifier oscillate? Thanks : ))

Hello Milan,

The THS4520 can be used in an MFB filter configuration.

Regards,
Loren

Hello Loren, many thanks for your response. I couldn’t believe to high speed parameters of this part so I ordered its evaluation kit. I have verified now that it is really perfectly stable at NG=1 and that it has 1200MHz GBW (I measured 1360 MHz at Av=13.8). I am really excited; it looks as perfect and unrivalled part for many applications : ))
