The LA4725 is a BTL two-channel power IC for car

audios developed in pursuit of excellent sound quality.

Low-region frequency characteristics have been improved

through the use of a new NF capacitorless circuit, and

crosstalk which causes “muddy” sound has been reduced

by improving both circuit and pattern layout. As a result

the LA4725 provides powerful bass and clear treble.




 High power: supports total output of 30 W+30 W. [EIAJ

power] (VCC=14.4 V, THD=30 %, RL=4)

⋅ Less pop noise.

⋅ Designed for excellent sound quality.

(fL<10 Hz, fH=130 kHz)

⋅ Any rise time settable by an external capacitor.

⋅ Standby switch circuit on chip. (microcontroller supported)

⋅ Various protectors on chip.

(output-to-ground short/ output-to-VCC short/ load

short/ overvoltage/ thermal shutdown circuit)

⋅ The LA4725 is pin-compatible with the LA4728.
