LC75344MD
Two-Channel Electronic Volume Control System
Overview The LC75344MD 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.
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. All settings are controlled by data input over a serial interface that conforms to the CCB* specifications.
