1LA4126,4126T monolithic linear IC || ARCUT ORAWING 2-CHANNEL AF POWER AMP. FOR TAPE Ca RECORDER, RADIO 30094 @ High output Features @ Built-in 2 channels enabling use in stereo and bridge amplifier applications. LA4126: 2.4W _ typ./channel, Vcc=9V, RL=4ohm, and 7.7W typ./bridge amplifier, Vcc=9V, Ri_=4ohm. LA4126T:4.2W typ./channel, Vcc=12V, RL=4ohm, and 9.0W typ./bridge amplifier, Vcc=9V, Ri_=8o0hm. Small pop noise at the time of power supply ON/OFF due to built-in muting circuit. Good ripple rejection due to built-in ripple filter. Soft tone at the time of output saturation. Good channel separation. Voltage gain fixed at 45dB (Bridge: 51dB). Variable voltage gain available with external resistor added. Pins for adjusting high frequency character- istics. Easy to design radiator fin. Low switching distortion at high frequencies. & Minimum number of external parts required: 9 pcs. min. (Stereo/bridge).
