Renesas Electronics M51132FP
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. Its built-in pass through function, in combination with an ALC amplifier, offers the capability of automatic level control.DESCRIPTION
Right/left independent volume control or right/left simultaneous volume control can be selected by DC voltages.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) Recommended Operating Conditions
● Supply voltage range: Vcc = 8 to 15 V
● Rated supply voltage: Vcc = 12 V System Configuration Rev.1.0, Sep.05.2003, page 1 of 11 M51132L/FP Pin Configuration IC Internal Block Diagram (M51132L) Rev.1.0, Sep.05.2003, page 2 of 11 M51132L/FP Pin
