SANYO LC75343M Datasheet

Ordering number : ENN6867

20901RM (OT) No. 6867-1/28

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.

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)

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)
