| This digital volume control has no pot to wear out and introduces almost no noise in the circuit. Instead, the volume is controlled by pressing UP and DOWN buttons. This simple circuit would be a great touch to any home audio project. |

| I really need this...Im thanking you guys for paging it into your web...this is great and very useful... | ||
| i really need a volume control mines gone =( | ||
| Hi There I am looking for a way to control the "Bride of Zen" pre-amp circuit so the I can replace the potentiometer at the end with a digital potentiometer or something similar. I would eventually want to control the volume via a microprocessor. Any ideas what I can do here. The voltage swing over the pot is 20V, and I find it hard to find digital pots that provide higher voltage support. Regards Jason | ||
| Now i like to test this circuit , I like small circuit design , but i don't know this one is perfect or not . But i like small and easy design | ||
| i think it would make a very good volume control but how about using it to control treble and bass of an amplifier. hey u all out there i need friends especially those interested in electronics so write if u're interested. | ||
| This project doesn't work because the IC is not biased correctly. The variable resistance must be DC biased at about half the supply voltage. It is easist to do if it has a positive and negative supply, then the resistance can have its low terminal connected to 0V. Its max allowed total supply voltage is 8V. It has linear steps, not logarithmic so it makes a poor volume control. It is good as a linear tone control. Stereo logarithmic digital volume control ICs are available. | ||
| I have make the circuit and using ds1669~10k. but the sound is not good and too slow. I can't hear anything except noise..can someone help me??? | ||
| I'm really fascinated with the circuit diagram, but I'm not finding the specified IC. Would you please let me know if there is any other alternative to it or another circuit diagram for volume control? I may also need a digital equalizer circuit diagram that would accompany the circuit. Thanks: I appreciate your works and projects. | ||
| If you want a sample od 1669 you can go to maximic.com and get a sample | ||
| This circuit performs the task of volume control, no external control is needed. Read the notes. | ||
