Volume Control Circuit Schematic Using DS 1669. Digital Volume Control Circuit. All audio amplifiers have some mechanism to increase and decrease volume. Most such mechanisms involve mechanical parts like a potentiometer. Here this project is to create an audio controller which works digitally. This is a very simple project which uses two switches and an IC to electronically control the

Digital Volume Control. 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. Parts: C1 – 0.1uf Ceramic Disc Capacitor. U1 – DS1669 Digital Pot IC (See Notes)

What’s Wrong With Digital Volume Controls?. With the obvious theoretical challenges overcome, 24-bit digital volume controls started to gain traction. Now that 24-bit sources are readily available, 24-bit volume controls seem unacceptable. Fortunately, volume controls with 32-bit or better precision are finding their way into DACs at a variety of price points.

BitPerfect: Digital Vs Analog Volume Control. If you implement volume control in the digital domain, every 6dB of attenuation results in the loss of one bit of resolution. If you play back music music with 24-bit bit depth, then all volume control results in irrecoverable loss of data via bit-depth reduction.

LM386 Based Stereo Audio Amplifier With Digital Volume Control. The supply voltage range for LM386 is wide (4-18 V). It can be powered with a +9V PP3 battery. For digital volume control feature, we will replace the external 10K potentiometer at the input stage with a digital potentiometer chip.
