I have a problem with an Analog Devices op-amp AD8397.
I’m using the attached circuit. The op-amp is really hot (around 60C with an
ambient of 25C) and I can’t explain why. All partx with a X are not installed.
Two resistors of 75k are installed to bias the inverter circuit input.
The rail +12V_TL is made with a TL431 from +24V_TL.
Please advise if you see anything obvious.
