• Operates from a +5V supply or dual supplies of up to ±6V.
• Nonvolatile (NV) on-chip memory to retain settings.
• Zero-crossing detection to minimize audio noise when adjusting the potentiometer setting.
• I²C serial interface for easy integration into a wide range of systems.
• Low power consumption, ideal for battery-operated devices.

Applications

The DS1807 is particularly well-suited for a variety of applications that require precise and noise-free volume control. Its typical applications include:

• Audio equipment such as amplifiers, mixers, and preamplifiers.
• Professional sound systems.
• Consumer electronics including home theater systems, TVs, and radios.
• Musical instruments.
• Computer audio systems.

Product Advantages

With its dual potentiometer design, the DS1807 allows for a reduction in board space and component count, providing a more efficient and cost-effective solution for designers. The logarithmic taper is specifically engineered to match the human ear's perception of sound volume, ensuring a smooth and natural volume adjustment. The inclusion of nonvolatile memory ensures that settings are preserved even after power is removed, which is critical for maintaining user preferences between uses.
