OPA699 Equivalent

One of our application circuit involves below stages

Photo diode > TIA(LTC6269)>OPA699(Inverter with G=10)>LTC6754(LVDS Out)

I want the soution to be arround complete Analog/LT ICs,i am also finding heat problems with OPA699

Kindly suggest an OPA699 equivalent with LT/Analog

  • Unfortunately i didn’t find an implementation in inverting mode in data-sheet, i did not get it worked for me, i connected it in inverting some how as shown below

    but it causes the problem of clamping of output waveform by 0.75V approximately also i dont see any clipping of voltage in negative side

    result

    green is input and blue is output

    i can share complete schema to you but i nee your personal mail id , i am not supposed to share on public forum
