MITSUBISHI SOUND PROCESSOR ICs. 2CH ELECTRONIC VOLUME-BALANCE

DESCRIPTION

The M51132 is a VCA (Voltage Controlled Amplifier) IC developed as an electronic volume control for audio-visual equipment. The IC is used to process small analog signals at the stage before power amplifier. Right/left independent volume control or right/ left simultaneous volume control can be selected by DC voltages. Its built-in pass through function, in combination with an ALC amplifier, offers the capability of automatic level control.

FEATURES

MTwo control modes can be selected (Left/right independent volume control mode or left/right simultaneous volume + balance control mode). Pass through switch is included to output the input signal Outline 14P5A(L) 8s it is, irrespective of the volume/balance control voltages. 1.27mm pitch 326mil ZIP WShock noise reduction pin is provided to reduce pass 2.8mm x 180mm x 6 See) through switch on/off shock noise.
