Overview

Ordering number : EN4799B CMOS IC LC7538JM Electronic Volume Control System for Car Audio Overview The LC7538JM is a fully equipped electronic volume IC which permits significant reductions in externally connected components while providing ample volume, balance, loudness, fader, bass and treble control functions.

• On-chip op amplifier for caching applications reduces external components.

• Reduced switching noise with silicon gate CMOS processor.

Key Features

Volume : 81 positions ranging from 0 dB to -79 dB (in 1 dB increments) plus -∞. Separate left and right control provides excellent balance function.
Loudness : Loudness operation provided by externally attached CR to activate tap at the -20 dB position of the volume ladder resistor.
Fader : Fader function traversing 16 positions with rear or front attenuated output only (these 16 positions consist of 2 dB step intervals ranging from 0 dB to -20 dB, 5 dB step i.
