LA4461N - Sanyo Semicon Device

LA4461N (LA4460N / LA4461N) 12W AF Power Amplifier

on the External Parts Recommended number of the external parts for the LA4460N/4461N is 8 as shown in the Sample Application Circuit 1. Namely they are : · Feedback capacitors 2 pieces 4.7µF/6.3V×2 · Starting time adjustmant resistor 1 pieace 1.5kΩ · Oscillation compensation capacitor 1 piece 0.01µF · Oscillation compensation C · R 4 pieces 0.033µF×2, 4.7Ω×2.

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 layo.
