Its only TSSOP packaging, 0.64mm pad spacing.  I get sufficient resolution for this type of IC package home brewing using acetate / UV  or   press-n-peel iron on resist.

Although, having said that, PCB manufacture of small numbers is getting quite cheap now.   Anyone who breadboards a successful design, lays out a PCB and puts a bit of money up front to get a few made would be guaranteed to get it back by passing the remaining PCBs onto others at a "sufficiently increased" cost to cover expenses.

I did that several times with PCBs for various synthesizer chips, and apart from the tedium involved with placing things in padded envelopes and addressing them, it's a good route to having PCBs made for your own stuff.

Of course, more tedium arrives when others need help getting your project going, but that's another story :-)

Anyone willing to do a run of pcb's for an amplifier using these ICs?
