A Cmos inverter makes a pretty distorted output because its output compesses the signal near the rail voltages. I made some fairly low distortion 0. One of the problems is that I can’t find two datasheets from the same manufacturer and different manufacturers are going to vary somewhat.

It’s not on the datasheet. They also might melt. The CD is not recommended by Texas Instruments.

BrownOut Banned Aug 13, Here is a link that explains the difference: What’s the difference between the CD and CD?

It looks like I’ll have to order some CDs or 74C04s then. Datasheets, Manuals or Parts. Here is a graph of the gain and frequency response of a CD or a 74C04 Cmos inverting amplifier:. Media New media New comments Search media. The CD is recommended instead if it has a single supply voltage. Thread starter Hero Start date Aug 13, Where did you get datazheet graph from?


I already have loads of CDs in my junk box, I’m just wondering if it’s worth buying some CDs as well. That app note was a great read!

That shouldn’t be a problem at low gains, due to negative feedback. By continuing to use this site, you are consenting to our use of cookies.

If they are used as a linear amplifier then they self-bias at an output voltage too low and with low gain. You must log in or register to reply here.

These and the CD are logic inverters that are always Un-Buffered. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at THey have different power supply schemes and the output circuitry is different. They sink 50mA but source only 8 ma with a 10V supply and an output voltage of 5V.

The lowpass filter reduced the 3rd harmonic distortion caused by the compression. Replacement Transformer Started by ncag Today at 7: It was fed the signal from a switched-capacitor lowpass filter IC and both were together in a feedback loop.


The CD parts that are for sale these days always have a U after the number, that is CDU and this is important. Electro Tech is an online community with overmembers who enjoy talking about and building cd40669 circuits, projects and gadgets. A classic application for an unbuffered part is when it is used as a clock oscillator.

Forums New posts Search forums. Not going to near either rail should also help. Is the answer 60? I’ve read through the datasheets and I’m ashamed to say I’m stuck.

Hero Banned Aug 14, The CD has symmetrical source and sink currents but not as high as 50mA. In this case the shorter propagation delay through the part, and slightly less complex transfer function means it oscillates at higher frequency and more reliably.
