Difference btwn TSSOP and SSOP?

post #1 of 4
Thread Starter 
Hi y'all,

I have a SSOP-28 piece (PCM2702). Can I use a BrownDog TSSOP-28 adapter for it? (In other words, what's the difference between SSOP and TSSOP?)

Thanks and sorry for the dumb question!

They are different.

One is Thin Shrink Small Outline Package, the other is Shrink Small Outline Package

Texas Instrument's website is too slow atm but Intersil's site has the following application notes:

http://www.intersil.com/data/pk/M28.15.pdf - SSOP

There are subtle differences which may affect the fit, I'd try and find the correct adapter.

Oh and on a side note, SSOP parts are a bastard to soldier. <looks painfully at my PCM1730>

The main difference between TSSOP and SSOP is the width of the pads or pins, the pitch between the two remains .65 mm the width of the pads varies from .30mm(tssop) to (.22-.38) SSOP.

 

Odds are a TSSOP part will fit a SSOP footprint. You need to be cautious the other way around. overall its likely that either way they will fit the footprint. When you by SSOP/TSSOP dev boards they usually use one footprint that will accommodate both types.
