Default Need help for LME49811

I am making a pcb layout of an LME49811 based amplifier using proteus 8. But I am not able to find the layout for LME49811. In the library it is absent. Please help me out so that I can make a pin layout for LME49811 in Ares.

Sorry, I use different software,
but the chips datasheet contains accurate package drawing of the chip including pin measurements and distances.

Hole diameter 0.7mm OK.
2.54mm raster between the two pin rows and backside of the pack.

Good luck with the modeling!

You can make your own footprint by following the package dimensions listed in the LME... data sheet. I have yet to lay out a PCB where I didn't have at least one custom footprint somewhere.

Modulus-86: 40W/8Ω @ 0.000061% THD. HP-1: 3W/20Ω, 450mW/300Ω @ 0.000032% THD. DG300B and Other Tube Circuits.
