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
Before anything else, I have few questions.
1. What is the frequency of operation?
2. Voltage/ Current range of the application.
3. Is this an old board or a complete new design? By this we can recommend a pin-to-pin replacement if necessary.
More details on the application would be of great help as well.
The direct replacement for OPA699 is AD8037.
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
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
