Can somebody help me identify this crystal oscillator for a quartz clock, my guess is that it is a 32,768 Hz crystal but the code says S523 and I have no idea what it means.
Ok guys, I'll go with the 472J so I'll get a 4.7nF.
I didn't knew if it needed to be replaced because I just couldn't read those values, now I tested it and says 0.032nf so I'm sure it lost its capacitance. By the way it's for a CCFL light, it's the cap near the tube that usually fails.
OK, Thanks pradeep!
Audioguru, that is because of all the wall adapters I have, ranging from cordless phones to laptop ones. I wanted to experiment with some of the features the IC includes (gain with a potentiometer, bass switch, 4 to 12 volts, etc...).
I will change the voltage regulator to...
That describes what my circuit does. The coaxial power supply is connected to the on-off power switch. The battery is connected to the switch in the coax jack.
Correct.
There's exactly where the problem lies because even though the battery is connected to the circuit and the jack is...
I thought someone might ask that :grin:.
It's kind of difficult describing it to me but the circuit has a main on/off switch that controls both inputs (battery and coaxial input) through their grounds.
What the coaxial input switch does is disconnect the battery from the coaxial input when...
Yes, I thought I could use a switch but there are three already in the circuit, it would be too much. The DC IN has a coaxial power input so it already comes with a switch that disconnects the battery automatically, I wanted to take advantage of that.
Hello I'm making an LM386 audio amplifier, the amp has the option to use DC or a battery (not at once of course), the problem is that the battery is getting drained really fast, I believe that's because the votage from the battery is getting back into the voltage regulator so I figured out I...
