LC75421M Datasheet | SANYO

Ordering number : ENN6866A CMOS IC Electronic Volume Controller for Cars Overview The LC75421M is an electronic volume controller that enables control of volume, balance, fader, bass/treble + super bass, input switching, and input and output level control functions using only a small number of external ponents. Features - On-chip buffer amplifier cuts down number of external ponents - 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 input (CCB) Functions - Volume: 0 d B to - 79 d B in 1-d B steps, and - ∞ (81 positions) Balance function with separate L/R control - Fader: rear output or front output can be attenuated across 16 positions (in 2-d B steps from 0 d B to 20 d B, 5-d B steps from - 20 d B to - 25 d B, 10-d B steps from - 25 d B to - 45 d B, and - 60 d B, - ∞) - Bass/treble: A tone control circuit can be configured using an external RC, with 15-position control from 0 d B to ±11.9 d B in 1.7-d B steps possible for both bass and treble - Input gain: 0 d B to +18.75 d B (1.25-d B steps) amplification is possible for the input signal. - Output gain: Fader output can be selected among 0 d B, +6.5 d B, and +8.5 d B. - Input switching: Five input signals can be selected for Left and for Right - Super bass: Step control with 11 positions is possible, with peaking characteristics (type T) Package Dimensions unit: mm 3263-MFP36SDJ (375 mil) [LC75421M] (0.8) SANYO: MFP36SDJ (375...
