LC75342 Datasheet PDF - Sanyo Semiconductor

●Overview

●The LC75342 and LC75342M are electronic volume and tone control systems that provide volume, balance, a 2-band equalizer, and input switching functions that can be controlled from serially transferred data.

●Features

●• On-chip buffer amplifiers minimize the number of external components.

●• Fabricated in a silicon gate CMOS process to minimize switching noise from internal switches.

●• Built-in analog ground reference voltage generation circuit.

●• All controls can be set from serially transferred data. Supports the CCB standard.

●Functions

●• Volume: 0 dB to –79 dB (in 1-dB steps) and –∞, for a total of 81 settings.

●  The volume can be controlled independently in the left and right channels to implement a balance function.

●• Bass boost: Up to +20 dB in 2-dB steps. Peaking characteristics.

●• Treble: ±10 dB in 2-dB steps. Shelving characteristics.

●• Selector: One of four sets of left/right inputs can be selected.

●• Input gain: The input signal can be boosted by from 0 dB to +30 dB in 2-dB steps.
