LC75343M
Electronic Volume Control System on-Chip
Overview
The LC75343M is an electronic volume system that can control the volume, balance, 2-band equalizer, super bass, and input switching functions by serial data input.
Note*: Regarding (Bass) and (Super bass) above, MID and BASS functions can also be realized by changing the capacitor capacitance.
Features
* On-chip buffer amplifier cuts down number of external components * Low switching noise generated by on-chip switch due to use of silicon gate CMOS process * On-chip reference voltage circuit for analog ground * Controls performed with serial data input (CCB)
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. (+/-10 dB control in 2-dB steps is possible depending on software support and the application. 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. * General-purpose amp (ATT): 2 on-chip general-purpose amplifiers (0-dB to -18-dB in 2-dB steps and - 11 positions attenuate control is possible, depending on software support and the application)
* CCB is a trademark of SANYO ELECTRIC CO., LTD.

Usage Cautions * Upon power application, the internal analog switch status is undefined. Use an external countermeasure such as muting until data is set. * When performing initial setting after applying power, send the initial setting data for the left and right channels prior to canceling mute. * To ensure that the high-frequency digital signals sent to the CL, DI, and CE pins do not spill over to the analog signal block, either guard these signal lines with a ground pattern, or perform transmission using shielded wires.
