I need a prototyping adapter for a ssop 24-pin package. Google turns up plenty of dip adapters for 5-7mm chips, but the chip I have is 3.9mm across the body and 6mm to the tips of the pins.

Anyone know of source of a suitable adapter? Doesn't necessarily have to be a dip, just something solderable by humans.

  • \$\begingroup\$ Common package dimensions here. Sounds like TSSOP. \$\endgroup\$

  • \$\begingroup\$ Thanks. The data sheets says SSOP, .650 spaced lands with nominal 5.3mm spcing for the centres of the lands. Silicon labs si4734/35. sparkfun.com/datasheets/Components/General/Si4734-35-C40.pdf \$\endgroup\$

Standard SSOP land pads should fit this device. 8.8mm from the extreme ends of the pads, width-wise, leaves 1.1mm on each side within which to solder, according to your 6mm measurement. The breakout board on Sparkfun's site looks like it has 1.5mm pads, but they just barely start at 6mm apart. These ones from Aries may be a better bet:

  • \$\begingroup\$ Thanks, they like they will do. I looked at the sparkfun ones, but the rows looked a little far apart, as did others I'd found. \$\endgroup\$

Some other sites that might carry something suitable - I've not ordered from any of them so I can't endorse them personally, but I thought the links might be helpful.
