2013年1月28日 · In theory at least, SOIC is half the pin pitch of DIP and SSOP is half again. Thus SSOP is 0.1/4 = 0.025" or 0.635mm. Except I see many parts, from TI and Linear especially, which are SSOP (or TSSOP)

2018年7月31日 · Some SOIC type of packages don't have a dot or semi-circle. The first row is designated by a bevel,

The SOIC is more than 50% longer than the TSSOP. (4.9mm vs. 3.0mm) and only a bit wider. That may not seem like a lot to you, but on a crowded board it might make a difference. The SOIC is taller (1.75mm vs. 1.2mm) which is enough to make a difference in a thin product. The lead pitch is much closer (almost half) on the TSSOP- 0.65mm vs. 1.27mm, so for crude …

2024年1月22日 · TI datasheet says: SOIC-16 Wide Body (DW) and Extra-Wide Body (DWW) Package Options It doesn't mention what DW stands for. I am annoyed when manufacturers come up with their own naming conventions without explaining clearly the accronymns or the logic behind the naming.

2017年7月21日 · I'm looking at two integrated circuit packages: SOIC and SOP. They seem (almost) identical (pitch, overall size, etc...) SOP SOIC Is there any important differences between these two packages th...

2023年6月9日 · Looking at the datasheet, we see a drawing of the required package on page 12: Here we can see the body of the part is 4.7-5.1mm long (nominal 4.9mm), and 3.8-4.0mm wide (nominal 3.9mm). The pin pitch is 1.27mm. This suggests you should use one of the parts labelled "3.9x4.9mmxP1.27mm" The acronym "EP" usually refers to some sort of thermal pad. Your …

2022年2月24日 · You could solder that in place of your SOIC-8, use the counterpart on the bottom of a small adapter board you're designing, and put the DIP on the other side of the board – might need to make the board a bit longish, to actually fit the DIP pins.

I do not know if this is on topic, but which are the recommended footprints dimensions (or a reference document) for the SOIC_N and MSOP_N Packages? In analog.com I can find only the outlines, and...

I read through the Wikipedia listing for SOIC and their list of packages but I did not find any references to "ESOP". So my main question is, what are the differences in ESOP (if any), and can I use this as a direct replacement for a standard SOP-8 chip?

2018年6月8日 · In Altium Designer, the L, M, N designators refer to the pad and footprint size. I believe these are from , but you need to pay for it. L east is 10% smaller than N; use for a really tight corner N is N ominal size M ost is 10% larger than N; relaxed, good for hand assembly All are compliant with the package size, so you can use any of them when laying out and the …
