Just got lm3875 and it won't fit in breadboard

[max97230]

Is there something I can get for a breadboard that lets me connect it? The LM3875 chip's pins are spaced too wide to get into the breadboard, and I think the pins themselves are too big even if they were spaced correctly. What am I supposed to get to use this thing?

Thanks!

Only 5 out of 11 pins actually do anything on this chip. Perhaps you could cut off the NCs and bend the remaining pins to fit some enlarged holes in a breadboard?

The other two alternatives are to build 'in the air' or to get a standard PCB from a source like eBay.

After cutting off the NC pins, would it fit better diagonally?

It fits perfectly if it is mounted diagonally. Don't break the extra pins, leave them for stability.

Here is a breadboard layout for a LM3875 as per the datasheet. R4 is mounted upright across adjacent tracks. It includes zobel components R5 and C5 which you can omit as required

Isn't that a "stripboard", not a "breadboard"? I always take breadboard to mean the solderless prototyping board like this:

yes,
the big pins of a chipamp will damage the receptacles of the plugboard.
I would call it a breadboard as well.

What pedants

Sorry, I always use the term wrong because I never bother with breadboard as with tinycad and veecad I can knock out a design for stripboard very quickly and if the circuit is right it always works with no worries over poor joints.

For reference the pins on a LM3875 will not fit in a BREADBOARD but will fit in a STRIPBOARD
