3024A-SIP10H

[LA4460N, 4461N]

SANYO : SIP10H

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 op-

eration.

• Soft tonal quality in saturated power output.

• Low distortion over low to high ranges of the audio fre-

quencies.

• 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 ampli-

fier 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.)
