LC75345M
Electronic Volume Control System on-Chip Overview
The LC75345M is an electronic volume system that can control the volume, balance, 2-band equalizer, super bass, and input switching functions by serial data input.
Functions
• Volume: 0 dB to –78 dB (1-dB step) and –∞ (64 positions) 0 dB to –50 dB (1-dB step), –50 dB to –70 dB (2-dB step), –70-dB to –78 dB (4-dB step) Balance function with separate L/R control
• Treble: ±10-dB control in 2-dB steps is possible. Shelving characteristic.
• Bass: ±10-dB control in 2-dB steps is possible. Peaking characteristics.
• Super bass: +10-dB control in 2-dB steps is possible. Peaking characteristics.
• Selector: 5 input signals can be selected both for L and R
• Input gain: 0 dB to +30 dB (2-dB step) amplification is possible for the input signal.
