LA4461N

Ordering number:ENN2660B Monolithic Linear IC LA4460N, 4461N 12W AF Power Amplifier for Car Radio, Car Stereo Features High gain of 51dB typ. and high power output of 12W typ. Possible to delete output and bootstrap capacitors, this encourages cost and space reductions due to external parts reduction. Reduced external components (8 pieces recommended, 6 pieces minimum). Almost no pop noises heard during power on or off operation. Soft tonal quality in saturated power output. Low distortion over low to high ranges of the audio frequencies. Low residual noises (Rg=0). Good operation conditions because of SIP (single ended pins) package having been employed for the LA4460N. All pin terminal layouts of the LA4461N are reversed for easy stereo PC board pattern arrengement. Two ground terminals for pre-amplifier and power amplifier are provided for easy PC board pattern arrangement and for stabilizing distortion chracteristics depending on signal source impedance. Voltage gain is fixed at 51dB, however, lowering the gain is possible by adding a resistor. IC is not damaged, if it is connected reversely. Audio muting functions (AC mute & DC mute) are equipped. Several protection circuits are installed, including : a. Thermal protection circuit. b. Overvoltage & surge voltage protection circuit. c. Load short-circuit current limiting protection circuit. d. Output pins DC short-circuit protection circuit. (grounding protection between OUT & GND, and speake...
