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)
Recommended Operating Conditions
•
•
Supply voltage range: Vcc = 8 to 15 V
Rated supply voltage: Vcc = 12 V

Volume/volume 1 control
Left/right simultaneous volume or channel 1 volume is
controlled by this value in the range of 0 to 5.2 V DC.

Pass through switch
shock noise reduction
Transit noise to the ear is softened by slowly switching
5.2 V for pass through
between pass through and VCA with time constant when and 0 V for VCA
the pass through switch is turned on/off. The time
constant is determined by externally connected
capacitor. T(sec) = 1.2 × C × 20k

Balance/volume 2 control Balance or channel 2 volume is controlled with 0 to 5.2 V
Pass through/VCA switch Operates as VCA with 0 V, and passes through the input
to output with 5.2 V
12
Control mode switch
Operates as channel 1 volume at pin 8 and as channel 2
volume at pin 10 with 0 V.
Operates as channel 1 and channel 2 simultaneous
volume at pin 8 and as balance at pin 10 with 5.2 V.
