Wuxi I-core Elec CD3312SA32.TB

CD3312 is an audio processing circuit featuring volume, tone (bass, treble), balance (left, right), and loudness (front, rear) control, designed for high-quality car audio and hi-fi audio systems. The circuit provides four stereo inputs with selectable gain and an external loudness control function. All controls are implemented via a serial I²C bus compatible with microprocessors. Utilizing high-performance bipolar/CMOS process technology, it achieves low distortion, low noise, and low DC level drift.
