The DS1802 is a digital stereo volume control IC component designed by Maxim Integrated. It is a versatile and compact device that offers excellent audio signal processing capabilities. Let's dive into its key features and overview:
1. Digital Volume Control: The DS1802 provides digital control over stereo volume, allowing precise and accurate adjustment of audio levels. It supports logarithmic (dB) volume control with 1.5 dB steps, ensuring smooth and incremental volume changes.
2. Dual Audio Channels: This IC component is specifically designed for stereo audio applications, providing separate volume control for both the left and right channels. It ensures balanced and synchronized volume adjustment, delivering high-quality audio output.
3. Wide Range of Attenuation: With a maximum volume attenuation range of 79.5 dB, the DS1802 supports both small and large reductions in audio output. Whether you need subtle volume adjustments or complete muting, this component covers a broad attenuation spectrum.
4. Nonvolatile Memory: One of the standout features of the DS1802 is its built-in nonvolatile memory. It enables the retention of volume settings even after power cycles, eliminating the need for reconfiguration every time the system is powered on.
5. Integrated Pushbutton Support: The DS1802 includes four integrated pushbuttons, making it easy to incorporate manual volume control functionality directly into your audio device. These buttons can be used to adjust volume, mute/unmute, or select predefined volume levels
