I will move that. Not something I do often so I have to remember.

What shall we call it?

Thought it might be a good time to take a panoramic picture of the backyard during Texas' fall. http://www.waynekirkwood.com/images/jpg/2646_Gladiolus_Backyard_Pano_112717_2_1024.jpg We're on an escarpment. Our creek is about 300 feet south and 60 feet downhill. There are mostly Eastern Red Cedar, E...

After soaking it in beer you might want to start a thread in the Design area of the forum. I'm liking this. Other than the analog front end for the measurement A/D and the balanced output there doesn't seem like much additional outboard circuitry would be required. Rather than a DPOT you might consi...

And you should.

One thing slightly off-topic is that the distortion in the pre-trimmed 2180 has a lower tempco (of distortion change) than the externally-trimmed 2181. The 2181, of an equivalent grade, can be trimmed lower than the 2180 but the 2180 will out-perform it over temperature. If I were going to do a &quo...

Sent a letter to THAT and it turned out I don't need tempcos for 2181 any more because it's already there on the chip. I don't think that's correct. If you look at the 2181 datasheet page 2 table 3 it shows a +0.33% gain control tempco. You still need -0.33% to correct it. Also see equation 1 on pa...

I probably need to buy a new cheapo VOM,,, the new stuff has many useful features the old stuff didn't.. probably one IC inside. :lol: No ICs in the 260. EMP-proof. I do have one of those credit card-sized DVMs and recently cleaned the selector switch. Its one IC chip-on-board inside an epoxy blob.
