I am sampath Bandara I need to construct composite amplifier so my desire gain is 45 and total bandwidth of 50 MHz with low noise and low offset voltage, high slew-rate. I highly appreciate if you can suggest me good two op amps for my circuit.
after that I create this circuit and I wont to know how can I insert the TT1-6-kk81 mini-circuit transformer in to the first input stage
I suggest you can use the AD8651/AD8652 part. AD8651/AD8652 has a bandwidth of 50 MHz at 5V supply, has low noise density of 4.5 nV/√Hz at 100 kHz, has a typical offset voltage of 100 uV and slew rate of 41 V/μs. You can download its datasheet in this link: http://www.analog.com/static/imported-files/data_sheets/AD8651_8652.pdf.
On the other hand, you can also try using our tool. The selection table for op amps parametric search, kindly view this link: Selection Table for Op Amps Parametric Search. It will help you to find lists of ADI op amps that is suitable to your design by entering multiple specifications.
By the way, what is your application?
I hope this helps.
