Ordering number : ENN7332 CMOS LSI LC75344M Two-Channel Electronic Volume Control System Overview The LC75344M is a two-channel electronic volume control IC that is controlled by data input over a serial interface. Functions • Volume control: 0 dB to –50 dB in 1 dB steps, –52 dB to –78 dB in 2 dB steps, and –∞, for a total of 66 positions. A balance function can be implemented by controlling the left and right channels independently. Package Dimensions unit: mm 3086B-MFP10S [LC75344M] Features • Built-in buffer amplifiers minimize the number of external components required. • Fabricated in a silicon gate CMOS process to minimize the switching noise generated by internal switches. • Built-in reference voltage generation circuit for the analog ground level.
