Details
12W AF Power Amplifier for Car Radio, Car StereoFeatures • 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 speaker protection provided.)
