LMH730033EVAL - PCB layer information

Hello Takushi-san,

The LMH730033EVAL is apparently a 2 layer board. You could build the LMH6502 on a 4 layer board with layout stack up as: top layer - VS+ layer - VS- layer and Bottom layer. Another layout stack up could be a 6 layer board with: top layer - GND - VS+ layer - VS- layer - GND and Bottom layer. For single supply operation of LMH6502, you could get rid of the VS- layer on a 6 layer board and have the VS+ layer sandwiched between two GND layers to essentially yield a 5 layer board.

If you are planning to build single supply LMH6502 on LMH730033EVAL board, you could hook up the VS- to GND and VS+ to the positive supply. Make sure that the input and output pins are within the common mode voltages for reliable operation.

Best Regards,

Rohit

Hello All,

I found the fab drawing on the LMH730033 EVAL board which I'm uploading for your information:

/cfs-file/__key/communityserver-discussions-components-files/14/4010.LMH730033-FabDwg-Hooman-7_5F00_8_5F00_15.pdf/cfs-file/__key/communityserver-components-

I might be able to get Gerber files, etc. on this board if need be. Just let me know and I'll try to get them and post them here.

Regards,

Hooman
