Overview
Ordering number : EN5348 CMOS LSI LC75371M Car Stereo Electronic Tone and Volume Control Overview The LC75371M is an electronic tone/volume control LSI that can implement, with minimal external components, volume, balance, fader, bass and treble, loudness, input switching, and input level controls.
Package Dimensions unit: mm 3204-MFP36S [LC75371M] Functions • Volume control: From 0 to –79 dB in 1-dB steps plus –∞ for a total of 81 settings.
Since the left and right levels can be set independently, this function can also be used to implement a balance function.
• Fader: Attenuates either the rear or front channels to one of 16 levels.
(Provides 16 settings, namely, from 0 to –20 dB in 2-dB steps, from –20 to –25 dB in one 5-dB step, from –25 to –45 dB in 10-dB steps, –60 dB, and –∞.
) • Bass and treble controls: Forms an NF-type tone control circuit (LUX type) using external capacitors.
Provides 15 settings each for the bass and treble controls.
• Loudness control: A loudness function can be implemented by attaching external RC circuits at the taps provided from the volume control resistor ladder starting at the –20-dB position.
• The input signal can be selected from one of three inputs for each of the left and right channels.
The input signal can be amplified by between 0 and +18 dB in 6-dB steps.
• Serial data input: Supports CCB* format communication with the system controller.
SANYO: MFP36S Features • Built-in buffer amplifiers allow applications to be implemented with few external components.
• A VDD/2 reference voltage generation circuit is provided on chip.
• CCB is a trademark of SANYO ELECTRIC CO.
, LTD.
• CCB is SANYO’s original bus format and all the bus addresses are controlled by SANYO.
