It’s not on the datasheet.

That shouldn’t be a problem at low gains, due to negative feedback. Articles Top Articles Search resources.

It works well as a linear amplifier. Very nice tear down and very in depth.

The bottom one is just a driver for the buzzer. If they are used as a linear amplifier then they self-bias at an output voltage too low and with low gain. The top one detects water and turns the power on. Thanks for the teardown. Click here to register now. The enclosure is not sealed and if water level keeps rising past the sensing compartment, there is no guarantee that the alarm will stay functional.

The bare board is made on week 17 of Its great you even were able to build the schematic from it. There is no battery low indicator, but at such a low drain it will take years for the battery to need replacement. Could the frequency of the sound be changed to lets say 1kHz?


Another strain relief on the battery wires to go over case plastic.

I’ve read through the datasheets and I’m ashamed to say I’m stuck. It looks like I’ll have to order datashewt CDs or 74C04s then. Rumor has it these last forever on a nine volt battery!

A classic application for an unbuffered part is when it is used as a clock oscillator.

Replacement Transformer Started by ncag Today datxsheet 7: Is the answer 60? Luckily it does not take much to make one on a design this simple. Board back- all throughole. 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.

Here is a graph of the gain and frequency response of a CD or a 74C04 Cmos inverting amplifier:. Since there is no hysteresis, the alarm will shut off the moment contacts stop touching water.

What’s the difference between the CD4009 and CD4069?

Keep linking good, informative sources. That app note was a great read! The lowpass filter reduced the 3rd harmonic distortion caused by the compression. Leave a Reply Cancel reply Your email address will not be published. To participate you need to cs4069ube.

The rainwater comes into quadrant III, and reaches the finished room before it gets to the drain or the sump. A Cmos inverter makes a pretty distorted output because its output compesses the signal near the rail voltages. THey have different power supply schemes and the output circuitry is different.

CD is so old, the datasheet is still from Harris. With sufficiently conductive fluid touching the two electrodes, the gate of Q1 gets pulled datsheet and it turns on. It appears Source and Drain are swapped in silk. They also might melt. The design is simple and pretty clever with essentially no battery drain until triggered. The design is nicely compartmentalized, with separate areas for sensor wiring, cd40699ube and electronics.

Where did you get that graph from?
