Datasheet Summary
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 ponents 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...
