LC75345M

Ordering number : ENN6868 CMOS IC 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. General-purpose amp (ATT): 2 on-chip general-purpose amplifiers 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) Package Dimensions unit: mm 3263-MFP36SDJ (375 mil) [LC75345M] 15.2 36 19 1 0.8 (0.8) 0.3 18 0.25 0.1 (2.25) 7.9 2.45max 10.5 0.65 SANYO: MFP36SDJ (375 mil) CCB is a trademark of SANYO ELECTRIC CO., LTD.
