LA4725: Audio Power Amplifier, Class AB, 30W ? 2ch, BTL
For complete documentation, see the data sheet
Product Description
The LA4725 is a 2-channel BTL audio power amplifier IC for Car audio. 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.
