M51132L - 2ch Electronic Volume

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

•Two 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 as it is, irrespective of the volume/balance control voltages.
•Shock noise reduction pin is provided to reduce pass through switch on/off shock noise.
•Built-in reference supply voltage circuit: output current 10 mA (Typ.)
•Maximum input: 3.4 Vrms (Typ.) (f = 1 kHz, THD = 1%)
•Low distortion: 0.005% (Typ.)
•Good channel separation: 102 dB (Typ.) (f = 1 kHz, Vo = 2 Vrms, IHF-A)
•Supply voltage range: Vcc = 8 to 15 V
•Rated supply voltage: Vcc = 12 V
