Title: So is anyone using smd mn3007 IC's
Post by: tone seeker on March 29, 2017, 03:36:34 AM
Well there's definitely a huge price difference, but I'm curious if
They work the same as regular mn3007 chips. I'm not real thrilled
With soldering those tiny leads, but I will if they work the same!

I've never seen a BBD in surface mount. If I could find them I wouldn't mind using them I suppose...

Do you have a link?  I've not seen these either.

I, too, have interest in this topic.  ;D

I'm gonna guess that the OP is basing his assumptions on the cost difference between other SMD components and their DIP counterparts (i.e. CD4047, CD4013, etc.) Assuming that if there were smd MN3007s that they would be cheaper.

I'm such a dummy! Or I just thought I found a solution to the end all concept of ever
Dwindling supply of parts.
Mouser tricked me! They put a D in frontof my MN....

LOL
Well, at least you didnt buy them, and adapters, and install them in a circuit!

Yea..... I was going to buy a boat load! Lol
I mean I know they make these in smd's to fit in those
Tiny pedals! Gotta get them somewhere!

Datasheet, datasheet, datasheet.

You know, that chip might make a decent voltage controlled resistor with a high frequency input ...

Are you thinking, like, using a variable PWM to turn the MosFET off and on fast enough to simulate a resistor?

Yah, like Freppo did with his phaser. Though the 4006 probably hard to beat on that count, especially since it has 4 switches on the chip. Might make for a cool tremolo, though.

I actually haven't seen that, but it sounds kind of like this:

I saw these a while back and was really excited too, until I read the data sheet :(
