M51132L Overview
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.
M51132L Key Features
- Two control modes can be selected. (Left/right independent volume control mode or left/right simultaneous volume + balan
- 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
