AD8397 getting hot

Hello there,

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.

Teodor
