LA4628
Two-Channel 20 W BTL Audio Power Amplifier
Overview
The LA4628 is a 2-channel general-purpose BTL audio
power amplifier provided in a miniature package. It was
designed for the best possible audio quality and features
an extended low band roll-off frequency provided by a
newly-developed NF circuit that does not require an
external capacitor. Furthermore, crosstalk, which can
cause muddiness in the audio output, has been
significantly reduced by both circuit and wiring pattern
improvements. Thus this amplifier can provide powerful
lows and clear highs.
Note that this device is pin compatible with the 13.5 W
×
2-channel LA4625, and allows end products differentiated
by their power rating to share the same printed circuit
board.
